Magnesium-stabilized amorphous calcium carbonate (Mg-ACC), amorphous magnesium calcium silicate hydrate (MCSH), and hydroxyapatite (HAp) are prepared by a precipitation method. By cold-pressing these particles, it is possible to produce porous bulk discs with a narrow pore size distribution. These porous inorganic discs (Mg-ACC, MCSH, and HAp) are investigated as stationary phases to study the chromatographic behavior and adsorption ability of rhodamine B, methylene blue, and ribonuclease. The adsorption affinities of different biomolecules can be easily observed and evaluated through this method. Furthermore, by infiltrating fabricated opaque porous discs with benzyl ether, which has a similar refractive index as the used inorganic particles (Mg-ACC, MCSH, and HAp), their optical properties significantly change and the discs become translucent. Moreover, by infiltrating the MCSH discs with a light-curing polymer, translucent composites with good surface hardness are fabricated. By doping particles with ions such as Ni2+, Co2+ , Fe3+, and Eu3+, the color and UV-visible spectrum of the bulk discs can be adjusted. Typically, by using iron-doped MCSH particles as the inorganic matrix, nanocomposites, which show a steep UV-absorption edge at 400 nm, are fabricated. Our work provides a simple and economical method to evaluate the affinity of biomolecules to inorganic materials and a novel way to fabricate translucent hard composite materials. The fabricated nanocomposite discs show a great UV shielding effect and superior surface hardness compared to polymethyl methacrylate and commercial sunglasses, suggesting their potential as new sunglass materials.

In this work, 1,4-diphenyltriphenylene-grafted (14.2%) polysiloxane (DPTP) was successfully synthesized and statically coated on capillary columns as a stationary phase for gas chromatography. The DPTP columns exhibited excellent efficiencies of 3646 plates m(-1) for a 30 m column and 3125 plates m(-1) for a 10 m column, as evidenced by naphthalene measurements at 120 degrees C, which demonstrated the good film-forming ability of DPTP. Thermogravimetric analysis showed that the weight of DPTP is reduced by 2% at 380 degrees C. Separation of the polyethylene pyrolysis product indicated that the maximum allowable operating temperature of the DPTP column is 360 degrees C. The moderate polarity of the DPTP column was investigated in terms of McReynolds constants. The DPTP column was utilized to separate analytes, including aromatic isomers, fatty acid esters, ethers, polycyclic aromatic hydrocarbons and their derivatives, and nitrogenous heterocyclic compounds, on the basis of the column’s strong pi-pi stacking, dipole-induced dipole, and dispersion interactions with solutes. In general, the DPTP column offers great potential as a novel stationary phase for separating various analytes due to its special structure and remarkable separation performance.

The liquid organic hydrogen carriers (LOHCs) are promising materials for hydrogen storage. The standard molar enthalpies of formation, Delta H-f(m)o (liq/cr) of diphenyl ether substituted with methyl, methoxy, and hydroxyl substituents were measured by the high-precision combustion calorimetry. Enthalpies of vaporization/sublimation Delta(g)(l,cr) H-o(m) (298.15 K) of these compounds were obtained by the transpiration method. Enthalpies of fusion of 2- and 4-hydroxy-diphenyl ether were measured by differential scanning calorimeter. Gas-phase enthalpies of formation Delta H-f(o)m (g, 298.15 K) of substituted diphenyl ethers calculated by the G4 method were in an excellent agreement with the experimental results. Enthalpies of the hydrogenation/dehydrogenation reactions of diphenyl ether derivatives were estimated and compared with the data available for other potential LOHC. A set of thermodynamic properties of diphenyl ether derivatives of benchmark quality was recommended for thermochemical calculations. Equilibrium temperatures of hydrogenation/dehydrogenation processes were calculated and compared with those of benzene derivatives. Because of their high hydrogen storage capacity, as well as very low volatility, these compounds could be considered as seminal candidates for LOHC.

Lignin is constructed from methoxylated phenylpropanoid with plenty of hydroxys and methoxys. Its conversion to valuable products is extremely attractive but especially challenging without additional hydrogen sources. Herein we report a hydrogen-free production of 4-alkylphenols directly from native lignin via self-reforming-driven depolymerization and hydrogenolysis over Pt/NiAl2O4. This is the first example of acquiring 4-alkylphenols from native lignin. Using this strategy, high yields of 4-alkylphenols, 17.3 wt %, were obtained from birch lignin. Reaction pathway and mechanism studies revealed that this strategy initiates from the reforming of aliphatic hydroxys, followed by the cleavage of C-O linkages, and ends via demethoxylation over Pt/NiAl2O4. Moreover, the subsequent aqueous phase reforming of the as-formed methanol accelerates the whole process. This strategy realizes the one-pot production of 4-alkylphenols from lignin by fully utilizing the structural hydrogen in lignin and H2O, providing a low-cost and safe method of lignin valorization.

An efficient bifunctional NbOPO4 supported Ru catalyst (Ru-NbOPO4) was applied to the hydrodeoxygenation of aromatic ethers and phenols and the upgrading of bio-oil. Characterization results revealed that the Ru-NbOPO4 catalyst possessed strong acidity, including Lewis and Bronsted acids. The Lewis acid sites originated from the Nb-O bonding structures, including slightly distorted octahedral NbO6, regular tetrahedral NbO4 and highly distorted octahedral NbO6. In combination with the strong acidity of the Nb-O species and excellent hydrogenation activity of the metallic Ru, the bifunctional Ru-NbOPO4 catalyst exhibited an excellent catalytic activity in the hydrodeoxygenation of aromatic ethers and phenols with different structures, and even real bio-oil to alkanes. The hydrocarbon yield after real bio-oil upgradation was up to 88.2 %. Carbon deposition and enlargement of the Ru nanoparticles resulted in slight deactivation of the catalyst. The catalytic activity could be mostly recovered after being calcined and reduced.

The stability of a and beta nanoporous-crystalline (NC) forms of Poly(2,6-dimethyl-1,4-phenylene) oxide (PPO), in the presence of guest molecules leading to crystallization in a and beta-form (alpha and beta-guests), is explored. Sorption of liquid guests at 30 degrees C and 60 degrees C is studied both for NC films and NC aerogels. WAXD and FTIR characterizations show that, for all considered conditions, NC alpha-phases after guest sorption/desorption remain unaltered. NC beta-phases, on the contrary, after alpha-guest sorption can be transformed in co-crystalline (CC) alpha-phases that after guest desorption are transformed in NC alpha-phases. All conducted experiments also show that possible planar orientations of NC films (c//or c perpendicular to orientations) remain essentially unaltered, after sorption of all considered guest molecules. The presently discovered beta ->alpha transition constitutes a route to obtain unoriented alpha-form films, which till now were not available by known preparation procedures.

Hydrodeoxygenation of lignin-derived phenols could be achieved generally with three reaction pathways: tautomerization, direct ring hydrogenation and direct C-O bond cleavage. The former pathway has been extensively studied over Pd/Fe catalyst in liquid-phase reaction, however, the contribution of the latter two is yet subject to further investigations. In this report, a comparative study of direct C-O bond cleavage and direct ring hydrogenation reaction pathways is presented on Pd/Fe, Fe and Pd/C catalysts using diphenyl ether as modelling compound. Despite its much higher activation energy than direct ring hydrogenation, direct C-O bond cleavage is dominant over Pd/Fe with much higher rates than the monometallic analogues due to the synergic catalysis of Pd-Fe. Based on this study and our previous results, the detailed reaction network for HDO of diphenyl ether is proposed. [GRAPHICS] .

The cleavage of C-O linkages in aryl ethers in biomass-derived lignin compounds without hydrogenation of the aromatic rings is a major challenge for the production of sustainable mono-aromatics. Conventional strategies over the heterogeneous metal catalysts require the addition of homogeneous base additives causing environmental problems. Herein, we propose a heterogeneous Ru/C catalyst modified by Br atoms for the selective direct cleavage of C-O bonds in diphenyl ether without hydrogenation of aromatic rings reaching the yield of benzene and phenol as high as 90.3 % and increased selectivity to mono-aromatics (97.3 vs. 46.2 % for initial Ru) during depolymerization of lignin. Characterization of the catalyst indicates selective poisoning by Br of terrace sites over Ru nanoparticles, which are active in the hydrogenation of aromatic rings, while the defect sites on the edges and corners remain available and provide higher intrinsic activity in the C-O bond cleavage.

A highly active difunctional Ni-Mg2Si/gamma-Al2O3 was prepared by thermally decomposing nickel tetracarbonyl onto gamma-Al2O3 impregnated with Mg2Si. The non-catalytic hydroconversion (NCHC) and catalytic hydroconversion (CHC) of the extract (E) and extraction residue (ER) from Yinggemajianfeng lignite were investigated over Ni-Mg2Si/gamma-Al2O3 at 240 degrees C in n-hexane. Benzyloxybenzene and oxybis(methylene)dibenzene were used as lignite-related model compounds to speculate the possible mechanisms for the catalytic hydrocracking and hydrogenation over Ni-Mg2Si/gamma-Al2O3. As a result, more organic matter in ER was converted to soluble portion (SP) by the CHC than by the NCHC. The main SP from the CHC are chain alkanes and cyclanes, while that from the NCHC is rich in arenes and oxygen-containing organic compounds. The results indicate that Ni-Mg2Si/gamma-Al2O3 effectively catalyze the hydrocracking of > C-alk-O-linkages and the hydrogenation of aromatic rings in E and ER.
