Highly efficient ZnO/WO nanocomposites towards photocatalytic gold recovery from industrial cyanide-based gold plating wastewater.

Discharging the gold-contained wastewater is an economic loss. In this work, a set of ZnO/WO was facile synthesized by hydrothermal method in order to recover gold from the industrial cyanide-based gold plating wastewater by photocatalytic process. Effect of ZnO contents coupled with WO was first explored.

Glycerol photocatalytic oxidation to higher value-added compounds via bismuth oxyhalide photocatalysts.

Bismuth oxyhalides (BiOX) including BiOCl, BiOBr, and BiOI, were well synthesized using solvothermal technique and then used in the aqueous phase photooxidation of glycerol as a catalyst. The as-synthesized BiOBr could achieve the highest glycerol transformation of around 85.6% in 8 h under ultraviolet light (UV) irradiation among as-synthesized BiOXs.

Ultrasound-Assisted Synthesis of Nonmetal-Doped Titanium Dioxide Photocatalysts for Simultaneous H Production and Chemical Oxygen Demand Removal from Industrial Wastewater.

A series of nonmetal-doped titanium dioxide (Nm /TiO, where is the weight fraction of nonmetal elements) photocatalysts was prepared via ultrasonic-assisted impregnation for simultaneous hydrogen (H) production and chemical oxygen demand (COD) removal from industrial wastewater. Three types of Nm elements, carbon (C), silicon (Si), and phosphorus (P), were explored. The P/TiO exhibited a higher photocatalytic activity for H production and COD removal than the C/TiO and Si/TiO photocatalysts.

Unusual synergetic effect of nickel single atoms on the electrocatalytic activity of palladium for alcohol oxidation reactions in alkaline media.

Palladium nanoparticles (Pd NPs) supported on Ni single atoms encapsulated in carbon nanotubes (NiSA) show a significantly enhanced electrocatalytic activity for the oxidation reactions of methanol, ethanol and glycerol in alkaline media due to an unusual electron withdrawal effect of NiSA on Pd NPs.
