Flower-like ZnO/SnS2 heterojunction was constructed as photocatalyst. The heterojunction shows hierarchical architecture structure, in which SnS2 nanosheets are uniformly decorated by ZnO nanoclusters. Compared to SnS2, the ZnO/SnS2 heterojunction displays improved photocatalytic efficiency for degradation of organic dye MB and hydrogen evolution. ...

In this paper, Ag-TiO2 photocatalysts with different Ag contents (1 mol%–5 mol%) were prepared and applied to cement mortar. The photocatalytic performance of Ag-TiO2 and photocatalytic cement mortar under UV light and simulated solar light was evaluated. The results showed that Ag loading on the surface of TiO2 could reduce its band gap width and ...

A novel visible light-driven AgBr/[email protected] catalyst was synthesized by a simple and rapid method. The composition and structure of the photocatalyst were characterized by XRD, SEM, UV-DRS, and XPS. It could be observed that the 2-methylimidazole zinc salt (ZIF-8) exhibited the rhombic dodecahedron morphology with the AgCl and AgBr particles evenl...

Photocatalytic water splitting is one of the promising approaches to solving environmental problems and energy crises. However, the sluggish 4e− transfer kinetics in water oxidation half-reaction restricts the 2e− reduction efficiency in photocatalytic water splitting. Herein, cobalt vanadate-decorated polymeric carbon nitride (named CoVO/PCN) was ...

One dimensional nanostructures based hybrids have proven to be potent for photocatalytic applications. The hybrids having modified interface play a vigorous role in enrichment of photocatalytic activity by electronic interaction. Electronic interaction at interface occurs by the formation of electronic barriers (Ohmic/Schottky) that affects the tra...

Ethylene glycol aqueous solution containing 0.5% NH4F was used as the electrolyte and the Ti foil was oxidized at 40 V for 30 min to obtain TiO2 nanotube arrays with an inner diameter of about 85 nm. After heat treatment at 450 °C for 2 h, the TiO2 nanotubes transformed from an amorphous phase to anatase, and a small percentage of the nanotubes col...
