On June 18, 2019, Wei, Kajia; Cao, Xiaoxin; Gu, Wancong; Liang, Peng; Huang, Xia; Zhang, Xiaoyuan published an article.HPLC of Formula: 321-28-8 The title of the article was Ni-Induced C-Al2O3-Framework (NiCAF) Supported Core-Multishell Catalysts for Efficient Catalytic Ozonation: A Structure-to-Performance Study. And the article contained the following:

During catalytic ozonation, Al2O3-supported catalysts usually have stable structures but relatively low surface activity, while carbon-supported catalysts are opposite. To encourage their synergisms, we designed a Ni-induced C-Al2O2-framework (NiCAF) and reinforced it with a Cu-Co bimetal to create an efficient catalyst (CuCo/NiCAF) with a core-multishell structure. The partial graphitization of carbon adjacent to Ni crystals formed a strong out-shell on the catalyst surface. The rate constant for total organic carbon removal of CuCo/NiCAF (0.172 ± 0.018 min-1) was 67% and 310% higher than that of Al2O3-supported catalysts and Al2O3 alone, resp. The metals on CuCo/NiCAF contributed to surface-mediated reactions during catalytic ozonation, while the embedded carbon enhanced reactions within the solid-liquid boundary layer and in the bulk solution Moreover, carbon embedment provided a 76% increase in ·OH-production efficiency and an 86% increase in organic-adsorption capacity compared to Al2O3-supported catalysts. During the long-term treatment of coal-gasification wastewater (∼5 m3 day-1), the pilot-scale demonstration of CuCo/NiCAF-catalyzed ozonation revealed a 120% increase in ozone-utilization efficiency (ΔCOD/ΔO3 = 2.12) compared to that of pure ozonation (0.96). These findings highlight catalysts supported on NiCAF as a facile and efficient approach to achieve both high catalytic activity and excellent structural stability, demonstrating that they are highly viable for practical applications. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).HPLC of Formula: 321-28-8

And the article contained the following:

The fluorescence of two-dimensional (2D) covalent organic frameworks (COFs) are generally quenched by the strong layer-layer π-π stacking or the intramol. rotation. However, the latter effect can be reduced if the intramol. rotation in COFs can be restricted through the selective coordination with metal ions or small mols. Herein, we demonstrate that the fluorescence of p-methoxyl group-substituted imine-based COFs can be dramatically enhanced after coordination with Al3+ compared with other metal cations (i.e. Fe3+, Ni2+, Cd2+, Mn2+, Co2+, Zn2+, Hg2+, Ba2+, Mg2+ and K+) while o-methoxyl group-substituted one has no such phenomena, which might be due to the rotation of the uncoordinated C=N and C-O bonds in one side. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Related Products of 150-78-7

On November 30, 2021, Wang, Dongdong; Gong, Wanbing; Zhang, Jifang; Han, Miaomiao; Chen, Chun; Zhang, Yunxia; Wang, Guozhong; Zhang, Haimin; Zhao, Huijun published an article.Name: 2-Methylanisole The title of the article was Encapsulated Ni-Co alloy nanoparticles as efficient catalyst for hydrodeoxygenation of biomass derivatives in water. And the article contained the following:

Catalytic hydrodeoxygenation (HDO) is one of the most promising strategies to transform oxygen-rich biomass derivatives into high value-added chems. and fuels, but highly challenging due to the lack of highly efficient nonprecious metal catalysts. Herein, we report for the first time of a facile synthetic approach to controllably fabricate well-defined Ni-Co alloy NPs confined on the tip of N-CNTs as HDO catalyst. The resultant Ni-Co alloy catalyst possesses outstanding HDO performance towards biomass-derived vanillin into 2-methoxy-4-methylphenol in water with 100% conversion efficiency and selectivity under mild reaction conditions, surpassing the reported high performance nonprecious HDO catalysts. Impressively, our exptl. results also unveil that the Ni-Co alloy catalyst can be generically applied to catalyze HDO of vanillin derivatives and other aromatic aldehydes in water with 100% conversion efficiency and over 90% selectivity. Importantly, our DFT calculations and exptl. results confirm that the achieved outstanding HDO catalytic performance is due to the greatly promoted selective adsorption and activation of C=O, and desorption of the activated hydrogen species by the synergism of the alloyed Ni-Co NPs. The findings of this work affords a new strategy to design and develop efficient transition metal-based catalysts for HDO reactions in water.

Teng, Kun-Xu; Niu, Li-Ya; Yang, Qing-Zheng published an article in 2022, the title of the article was A host-guest strategy for converting the photodynamic agents from a singlet oxygen generator to a superoxide radical generator.Category: ethers-buliding-blocks And the article contains the following content:

Type-I photosensitizers (PSs) generate cytotoxic oxygen radicals by electron transfer even in a hypoxic environment. Nevertheless, the preparation of type-I PSs remains a challenge due to the competition of triplet-triplet energy transfer with O2 (type-II process). In this work, we report an effective strategy for converting the conventional type-II PS to a type-I PS by host-guest complexation. Electron-rich pillar[5]arenes are used as an electron donor and macrocyclic host to produce a host-guest complex with the traditional electron-deficient type-II PS, an iodide BODIPY-based guest. The host-guest complexation promotes intermol. electron transfer from the pillar[5]arene moiety to BODIPY and then to O2 by the type-I process upon light-irradiation, leading to efficient generation of the superoxide radical (O2- ). The results of anti-tumor studies indicate that this supramol. PS demonstrates high photodynamic therapy efficacy even under hypoxic conditions. This work provides an efficient method to prepare type-I PSs from existing type-II PSs by using a supramol. strategy.

Synthesis of new Schiff′s base Zn-complexes for photo-oxidation of Me arenes and xylenes are reported under visible light irradiation conditions. All the synthesized new ligands and Zn-complexes are thoroughly characterized with various spectral analyses and confirmed as 1:1 ratio of Zn and ligand with distorted octahedral structure. The bandgap energies of the ligands are higher than its Zn-complexes. These synthesized new Zn(II) complexes are used for the photo-fragmentation of organic dye pollutants, photodegradation of food industrial wastewater and oxidation of Me arenes which are converted into its resp. aldehydes with moderate yields under visible light irradiation The photooxidation reaction dependency on the intensity of the visible light was also studied. With the increase in the dosage of photocatalyst, the Me groups are oxidized to get aldehydes and mono acid products, which are also identified from LC-MS data.
