This communication describes an efficient co-catalyst Co3O4 nanoparticle with a tunable two-electron water oxidation reaction pathway in photoelectrochemical H2O2 production. The photoluminescence measurement explains that the promotion effect is due to the accelerated activation of water to ˙OH. The increased Faraday efficiency of H2O2 for the Co3O4/WO3 sample also verifies that the promotion effect to a two-electron water oxidation reaction of Co3O4 is universal to other semiconductor photoanodes.
本通讯描述了一种高效的共催化剂 Co3O4 纳米粒子,其在光电化学 H2O2 生成中具有可调谐的两电子水氧化反应途径。光致发光测量表明,这种促进作用是由于水加速活化为˙OH。Co3O4/WO3 样品的 H2O2 法拉第效率增加也验证了 Co3O4 对两电子水氧化反应的促进作用对其他半导体光阳极是普遍适用的。
