Visible light photocatalysis: efficient Z-scheme LaFeO/g-CN/ZnO photocatalyst for phenol degradation.

In this work, a Z-scheme LaFeO/g-CN/ZnO heterojunction photocatalyst with large specific surface (68.758 m/g) and low cost (0.00035 times the cost of per gram of Au) was easily synthesized by glucose-assisted hydrothermal method.

Enhanced catalytic peroxymonosulfate activation over carbon shells encapsulating cobalt ferrite radical and nonradical routes.

Well-defined carbon shells encapsulating CoFe2O4 deliver superior performance in catalytic PMS activation for organics degradation with a reaction rate constant of 0.269 min-1, 4.7 times the hollow CoFe2O4 and 2.

Highly efficient and stable p-LaFeO/n-ZnO heterojunction photocatalyst for phenol degradation under visible light irradiation.

A series of catalysts with p-LaFeO/n-ZnO heterostructure were designed and prepared by hydrothermal method. The structure, surface topographies, optical properties and interfacial interactions of these photocatalysts were analyzed by XRD, SEM, TEM, PL, Uv-vis DRS, XPS, COD, TOC etc., indicating that p-n heterojunction formed at the interface between p-LaFeO and n-ZnO, which enhanced the photocatalytic activity.

A Co-Fe Prussian blue analogue for efficient Fenton-like catalysis: the effect of high-spin cobalt.

Herein, we, for the first time, report a high spin Co-Fe Prussian blue analogue (Co-Fe PBA) as a highly efficient Fenton-like catalyst for sulfate radical (SO˙) production. Our experiments and density functional theory (DFT) calculations show that the largely elongated SO-OH bond length, strengthened adsorption and facilitated electron transfer for peroxymonosulfate (PMS) activation catalyzed by high-spin (HS) Co are the main factors contributing to its excellent activity.

Shape-Controlled Synthesis of Metal-Organic Frameworks with Adjustable Fenton-Like Catalytic Activity.

Controllable synthesis of metal-organic frameworks with well-defined morphology, composition, and size is of great importance toward understanding their structure-property relationship in various applications. Herein, we demonstrate a general strategy to modulate the relative growth rate of the secondary building units (SBUs) along different crystal facets for the synthesis of Fe-Co, MnFe-Co, and Mn-Co Prussian blue analogues (PBAs) with tunable morphologies. The same growth rate of SBUs along the {100}, {110}, and {111} surfaces at 0 °C results in the formation of spherical PBA particles, while the lowest growth rate of SBUs along the {100} surface resulting from the highest surface energy with increasing reaction temperature induces the formation of PBA cubes.

The role of KCl in FeCl-KCl/AlO catalysts with enhanced catalytic performance for ethane oxychlorination.

Among the vinyl chloride production processes, ethane oxychlorination is the most economical and environment-friendly process but constrained by the lack of high performance catalysts for industrial applications. In this work, FeCl-KCl/AlO catalysts with different molar ratios of K/Fe were prepared by a co-impregnation method and applied to ethane oxychlorination. The FeCl-KCl/AlO catalyst with K/Fe = 2 exhibited enhanced catalytic performance with the highest conversion of CH (99.

A novel p-LaFeO3/n-Ag3PO4 heterojunction photocatalyst for phenol degradation under visible light irradiation.

A novel heterojunction photocatalyst p-LaFeO3/n-Ag3PO4 has been prepared via a facile in situ precipitation method. It exhibits higher activity than individual Ag3PO4 and LaFeO3 in the degradation of phenol. The excellent activity is mainly attributed to its more effective separation of electron-hole pairs.

Ultrasound-mediated synthesis of 4-substituted 1,4-dihydropyridine-3,5-dicarboxylates catalyzed by 1-carboxymethyl-3-methylimidazolium tetrafluoroborate under solvent free condition.

4-Substituted 1,4-dihydropyridine-3,5-dicarboxylates (4) have been synthesized by the solvent-free reaction of aldehyde, methyl propiolate and ammonium carbonate catalyzed by ionic liquid 1-carboxymethyl-3-methylimidazolium tetrafluoroborate under ultrasonic irradiation. The effects of changes in the ultrasonic power, temperature, catalysts and reactants on the synthesis of 4-substituted 1,4-dihydropyridine-3,5-dicarboxylates (4) are discussed. With the optimized reaction conditions, various aldehydes were used to synthesize 1,4-dihydropyridines (4) under the influence of ultrasound irradiation.

Ultrasound-mediated synthesis of ,-bis(phenacyl)aniline under solvent-free conditions.

Abstract: An efficient method for the synthesis of ,-bis(phenacyl)anilines was developed via smooth condensation of anilines with α-bromoacetophenones in the presence of sodium carbonate as acid acceptor and polyethylene glycol 400 (PEG 400) as catalyst at room temperature under solvent-free conditions by using 350 W ultrasound irradiation. In addition to experimental simplicity, the main advantages of the procedure are mild conditions, short reaction times (30-45 min), and high yields (73-83 %).
