摘要

研究发现，少量添加 E TeIV 物种（< 1 at%）可显著提高多晶锐钛矿二氧化钛的可见光光催化活性。这种效应可初步归因于掺杂剂立体化学活性孤电子对 E 中和了邻近表面的氧空位，该空位是光生空穴和电子的重组中心。

A particular mechanism of the effect of lone pair E TeIV dopant atoms on visible-light photocatalytic activity of anatase TiO2

It was found that small additives of E Te^IV species (< 1 at%) notably enhance the visible-light photocatalytic activity of polycrystalline anatase TiO₂. This effect can tentatively be attributed to the neutralization of the neighboring surface- located oxygen vacancy, acting as a recombination center for photogenerated holes and electrons, by the dopant stereochemically active lone electron pair E.

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.
