光电催化水分解是利用太阳能解决能源短缺的有效途径。wo3的价带边缘位于~ 3vvs。正常氢电极(NHE),它可以提供足够的电位来动态氧化水进行析氧反应。然而,仅使用wo3作为光阳极时,水氧化反应动力学缓慢。使用助催化剂来促进反应动力学是非常可取的。通过光沉积法将mnox负载在wo3光阳极上,提高了光电化学水氧化性能。复合光阳极的光电流密度在沉积时间为3 min时达到最大值,比原始wo3光阳极高出约40%。二氧化锰不仅是水裂解的助催化剂,而且是提高氧化选择性的助催化剂。我们尝试用两种方法来加载MnOxon wo3光阳极材料。结果表明,在wo3光沉积中加入适量的mnox可以提高wo3光阳极的性能。
Photoelectrocatalytic water splitting is an effective way to utilize the solar energy to solve the energy shortage. The valence band edge of WO3located at ∼3 Vvs.normal hydrogen electrode (NHE), which can offer enough potential to kinetically oxidize water for oxygen evolution reaction. However, water oxidation reaction kinetics is sluggish when only WO3is used as the photoanode. It is highly desirable to use cocatalyst to promote the kinetics. MnOxloaded on the WO3photoanode through photodeposition methods improves the photoelectrochemical water oxidation performance. A maximum photocurrent density of composite photoanode is achieved with a deposition time of 3 min, which is higher than that of pristine WO3photoanode around 40%. MnO2is not only a cocatalyst for water splitting but also for improving oxidation selectivity. We tried to use two means to load MnOxon WO3photoanode material. It is observed that loading a moderate amount of MnOxon the WO3by photodeposition can promote the performance of the WO3photoanode.
