溶液中光诱导的电子转移反应已进行了大量的研究。而半导体粉末在水相或非水溶剂中的光化学研究也与自俱增。这种光化学与成像体系、太阳能转换以及光催化或污物的光降解有关。因此,越来越引起人们的重视。 Harbour和Hair用自旋捕捉技术研究了在ZnO-H_2O的分散体系中光合成过氧化氢,并检测到羟基自由基。他们认为氧化锌可能通过水的氧化将O_2还原成H_2O_2,从而使太阳能转换成化学能。人们自然会想到ZnO在其它溶剂中是否-也能观察到溶剂光氧化
A large number of studies have been conducted on light-induced electron transfer reactions in solution. Photochemical studies of semiconductor powders in aqueous or non-aqueous solvents have also increased. This photochemistry is related to imaging systems, solar energy conversion, and photodegradation of photocatalysis or dirt. Therefore, more and more people’s attention. Harbor and Hair studied the photo-synthesis of hydrogen peroxide and the detection of hydroxyl radicals in a ZnO-H 2 O dispersion by spin-capture technique. They think that zinc oxide may reduce O_2 to H_2O_2 through the oxidation of water, so that solar energy can be converted into chemical energy. It is natural to think of whether or not ZnO is in other solvents - the photooxidation of solvents is also observed
