摘要

均相氧合的氯酚水溶液，经过光降解(λ >通过多金属氧酸盐W10O4−32,PW12O3−40和SiW12O4−40将CO2和Cl−转化为CO2和Cl−。在没有双氧的情况下，矿化也会发生，但这个过程要慢一个数量级以上。在双氧存在下，比较了这些催化剂与TiO2悬浮液的有效性。

Photocatalytic degradation of chlorophenols to CO2 and HCl with polyoxotungstates in aqueous solution

Homogeneous oxygenated aqueous solutions of chlorophenols, undergo photodegradation (λ > 320 nm) to CO₂ and Cl⁻ by polyoxometalates W₁₀O⁴⁻₃₂, PW₁₂O³⁻₄₀, and SiW₁₂O⁴⁻₄₀. Mineralization takes place, also, in the absence of dioxygen but the process is more than an order of magnitude slower. In presence of dioxygen the effectiveness of these catalysts compares with TiO₂ suspension.

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.
