A novel and highly active zeolite Y/ZSM-5 composite zeolite (CZ)-supported nickel catalyst (Ni/CZ with 10% of Ni loading) was prepared by modified deposition-precipitation to uniformly disperse Ni nanoparticles (NNPs) onto CZ. Hecaogou subbituminous coal was exhaustively extracted with isometric carbon disulfide/acetone mixed solvent to afford the extractable portion and inextractable portion (IEP). Ethanol-soluble portion (ESP) was obtained by ethanolyzing the IEP at 300 degrees C and subjected to catalytic hydroconversion (CHC) over Ni-10%/CZ at 160 degrees C to afford catalytically hydroconverted ESP (CHCESP). Both ESP and CHCESP were analyzed with a Fourier transform infrared spectrometer, gas chromatograph/mass spectrometer (GC/MS), and quadrupole exactive orbitrap mass spectrometer. The results show that the relative contents (RCs) of both chain alkanes and hydroarenes in CHCESP are significantly higher than those in ESP and cyclanes and alkenes were only detected in CHCESP, while the RCs of both arenes and oxygen-containing organic compounds in CHCESP are much lower than those in ESP and nitrogen- and/or sulfur-containing organic compounds were only detected in ESP with GC/MS. According to the CHC of oxybis(methylene)dibenzene (OBMDB), Ni-10%/CZ can effectively activate H-2 to biatomic active hydrogen (H center dot center dot center dot H) and the resulting H center dot center dot center dot H was heterolytically split into an immobile H- attached on Ni/CZ and a mobile H+. H+ transfers to an oxygen atom (OA) in OBMDB and cleaves the C-O bridged bond to produce phenylmethanol (PM) and benzylium, followed by H- abstraction from the Ni/CZ surface by benzylium to form toluene. H+ transfer to the OA in PM also leads to the cleavage of the C-O bond in PM to produce H2O and benzylium, which abstracts H- from the Ni/CZ surface to yield toluene. H center dot center dot center dot H transfer to the benzene ring in toluene generates methylcyclohexane. Therefore, Ni-10%/CZ catalyzes both H+ and H center dot center dot center dot H transfer. In addition, it proved to be stable for the CHC of OBMDB after 3 cycles.

The coupling reactions of phenols and nitrogen hetereocycles with aryl halide were catalyzed by a highly active, readily available and easily recoverable heterogeneous Cu catalyst which was prepared by simply stirring an suspension of chitosan in solvent with copper compound. The result showed that chitosan@Cu2O catalyst catalyzed the coupling reactions of aryl halides with phenols and nitrogen hetereocycles to readily give the corresponding products in moderate to excellent yields. The highly active catalyst can be reused many times without losing its catalytic activity.

A rapid, sensitive, and practical QuEChERS method coupled with gas chromatography-mass spectrometry was developed for the simultaneous determination of 16 chemical adjuvant residues in samples of fruits (apple, nectarine, grape) and vegetables (tomato, cucumber, spinach). All target compounds were separated in less than 16 min. Samples were extracted with acetonitrile, and the types of extraction salt and cleanup sorbent were optimized. The optimized method was validated by evaluating the linearity, accuracy, precision, and matrix effect. The recoveries of the 16 pesticides adjuvants ranged from 61.2 to 116.3% with relative standard deviations lower than 11.6%. Limits of detection ranged from 0.21 to 3.02 mu g/kg, and limits of quantification ranged from 0.71 to 10.07 mu g/kg. Finally, the developed method was successfully employed to identify and quantify pesticide adjuvant residues in the analysis of 30 real fruit and vegetable samples.

Electrical conductivity, mechanical flexibility, and large electroactive surface areas are the most important factors in determining the performance of various flexible electrodes in energy storage devices. Herein, a layer-by-layer (LbL) assembly-induced metal electrodeposition approach is introduced to prepare a variety of highly porous 3D-current collectors with high flexibility, metallic conductivity, and large surface area. In this study, a few metal nanoparticle (NP) layers are LbL-assembled onto insulating paper for the preparation of conductive paper. Subsequent Ni electroplating of the metal NP-coated substrates reduces the sheet resistance from approximate to 10(3) to <0.1 omega sq(-1) while maintaining the porous structure of the pristine paper. Particularly, this approach is completely compatible with commercial electroplating processes, and thus can be directly extended to electroplating applications using a variety of other metals in addition to Ni. After depositing high-energy MnO NPs onto Ni-electroplated papers, the areal capacitance increases from 68 to 811 mF cm(-2) as the mass loading of MnO NPs increases from 0.16 to 4.31 mg cm(-2). When metal NPs are periodically LbL-assembled with the MnO NPs, the areal capacitance increases to 1710 mF cm(-2). HPLC of Formula: C14H14O.
