Catalytic activity of MoO3:V2O5 mixed oxides towards oxidation reactions: the nature of catalytic centers

Singlet oxygen emission and peroxide generation at the surface of molybdenum–vanadium oxides evidenced that the catalytic activity of a MoO₃:V₂O₅ mixed oxide at 70–175 °C was governed by the formation of peroxo groups in the interaction of molecular oxygen with adjacent V^iv surface centers; the thermolysis of these groups yielded singlet oxygen capable of oxidizing selectively alcohols to aldehydes.

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
