Abstract

Decatungstate ((nBu₄N)₄W₁₀O₃₂, marked as DTs) and PMo_12-nV_n could be easily synthesized via polymerization in acidic aqueous solution. They can efficiently catalyze the oxidation of cyclohexane to afford cyclohexanone and cyclohexanol under visible light, affording about 30% conversion in the presence of additive HCl. This is the first example to show the influence of HCl on oxidizing capacity for DTs and PMo_12-nV_n. It was found that PMo_12-nV_n could induce the generation of chlorine radical in the presence of HCl, playing a significant role to realize the oxidation of cyclohexane.

盐酸对十钨酸盐或 PMo12-nVn 光催化氧化环己烷的影响

癸钨酸盐（(nBu4N)4W10O32，标记为 DTs）和 PMo12-nVn 可在酸性水溶液中通过聚合反应轻松合成。在可见光下，它们能有效催化环己烷的氧化反应，生成环己酮和环己醇，在添加盐酸的情况下，转化率约为 30%。这是第一个显示盐酸对 DTs 和 PMo12-nVn 氧化能力影响的实例。研究发现，PMo12-nVn能在盐酸存在下诱导氯自由基的生成，对实现环己烷的氧化起着重要作用。

期刊介绍： Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
