A highly efficient third generation catalyst, CaCu3Ti4O12 (CCTO) shows excellent photoelectrochemical (PEC) and photocatalytic ability. As only 4% part of the solar spectrum covers UV light, thus it is highly desirable to develop visible light active photocatalyst materials like CCTO for effective solar energy conversion. A direct band transition with a narrow band gap (1.5 eV) was observed. Un...

Photoelectrocatalysis is a novel technique that combines heterogeneous photocatalysis with the application of an electric field to system through electrodes for degradation organic contaminants in aqueous systems, mainly toxic dyes. The efficiency these combined processes depends on semiconductor properties catalysts, as well anodic capacity electrode. In this study, we propose use active hydro...

Chemicals and Materials All chemicals used in the experiments (KBr, Fe2(SO4)3, H2SO4, ethanol, Rhodamine B) are analytical grade or better provided by Sinopharm Co., China. All aqueous solutions are prepared with deionized water (18.2 MΩ, Milli-Q, Millipore Corp., France). ITO glass slides were washed in an ultrasonic cleaner by isopropanol and deionized water for several times and dried by blo...

Oilfield produced water was treated by photocatalysis, electro-oxidation, and photoelectrocatalysis, respectively. The chemical composition and toxicity of the raw effluent and treated products were assessed by chemical and mutagenicity analysis. The raw effluent exhibited mutagenic activity in both strains of Salmonella typhimurium. The lowest concentration of the dichloromethane extract capab...

Photoelectrocatalysis offers the opportunity to close carbon loop and convert captured CO2 back into useful fuels feedstocks, mitigating against anthropogenic climate change. However, since is inherently stable...
