Photocatalytic CO2 reduction seems potential to mitigate greenhouse gas emissions and produce renewable energy. A new model of photocatalytic CO2 reduction in optical fiber monolith reactor with multiple inverse lights was developed in this study to improve the conversion of CO2 to CH3OH. The new light distribution equation was derived, by which the light distribution was modeled and analyzed. ...

Three-dimension ordered macroporous (3D-OM) bismuth vanadates with a monoclinic crystal structure and high surface area (18-24 m(2) g(-1)) have been prepared using ascorbic acid (AA)- or citric acid (CA)-assisted poly(methyl methacrylate) (PMMA)-templating strategy with bismuth nitrate and ammonium metavanadate as the metal sources, HNO(3) as the pH adjuster and ethylene glycol and methanol as ...

Photocatalytic conversion of cellulose to sugars and carbon dioxide with simultaneous production of hydrogen assisted by cellulose decomposition under UV or solar light irradiation was achieved upon immobilization of cellulose onto a TiO2 photocatalyst. This approach enables production of hydrogen from water without using valuable sacrificial agents, and provides the possibility for recovering ...

This paper discloses the first example of photocatalytic direct decarboxylative hydroxylation of carboxylic acids. It enables the conversion of a variety of readily available carboxylic acids to alcohols in moderate to high yields. This unprecedented protocol is accomplished under extremely mild reaction conditions using molecular oxygen (O2) as a green oxidant and using visible light as a driv...

Herein, we demonstrate a complex-precipitation strategy for high-yield fabrication of single-crystalline Ag(3)PO(4) sub-microcubes with sharp corners, edges, and smooth surfaces, which exhibit much higher photocatalytic activities and photoelectric conversion properties than spherical Ag(3)PO(4) particles and commercial N-doped TiO(2) under visible light irradiation.
