查询词典 pollutants

Mechanistically, the photocatalytic processes are based on the electron transfer from a excited dyes to the conduction band of TiO〓 semiconductor and subsequent some reactions such as the further reaction of injected electrons with adsorbed oxygen and complicated decomposition processes of dye cationic radicals to lead to dye degradation or mineralization, which offers a feasibility of utilizing inexpensive visible light or most part of solar spectra to treat dye pollutants.

其光催化过程的机理为：染料在可见光下被激发，电子从激发态染料传输到TiO〓半导体的导带，随后发生一系列的反应，如注入的电子与吸附的氧反应以及染料正碳自由基复杂的分解反应导致了染料的降解和矿化，这就为利用廉价的可见光或太阳光中的大部分可见光谱来处理染料污染物提供了可能。
