Abstract
The catalytic reduction of CO2 has been performed over Prussian blue-deposited TiO2 particles, and the products were methanol, ethanol, acetaldehyde and acetone with a negligibly small amount of methane. The deposition of Prussian blue (PB) onto TiO2 particles was accomplished under the irradiation of light, and on this occasion PB was further reduced to ES (reduced form of PB). The hydrogenation Of CO2 taking place in dark was caused by the reaction with active hydrogen atoms generated in the redox reaction consisting of the oxidation of ES to PB and the reduction of H2O. The deactivated catalyst was restored in KCl aqueous solution under the illumination of light by photo-rereducing PB to ES.
期刊介绍：
Journal of Molecular Catalysis (China) is a bimonthly journal, founded in 1987. It is a bimonthly journal, founded in 1987, sponsored by Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, under the supervision of Chinese Academy of Sciences, and published by Science Publishing House, which is a scholarly journal openly circulated both at home and abroad. The journal mainly reports the latest progress and research results on molecular catalysis. It contains academic papers, research briefs, research reports and progress reviews. The content focuses on coordination catalysis, enzyme catalysis, light-ribbed catalysis, stereochemistry in catalysis, catalytic reaction mechanism and kinetics, the study of catalyst surface states and the application of quantum chemistry in catalysis. We also provide contributions on the activation, deactivation and regeneration of homogeneous catalysts, solidified homogeneous catalysts and solidified enzyme catalysts in industrial catalytic processes, as well as on the optimisation and characterisation of catalysts for new catalytic processes.
The main target readers are scientists and postgraduates working in catalysis in research institutes, industrial and mining enterprises, as well as teachers and students of chemistry and chemical engineering departments in colleges and universities. Contributions from related professionals are welcome.
