UV-light irradiation to TiO(2) in an aqueous ethanol solution of (NH(4))(2)MoS(4) under deaerated conditions has yielded molybdenum(IV) sulfide nanoparticles on a TiO(2) surface (MoS(2)/TiO(2)) to be transformed into molybdenum(VI) oxide species highly dispersed at a molecular level by a subsequent heating at 773K in air (m-MoO(3)/TiO(2)). In HCOOH aqueous solutions, the MoS(2)/TiO(2) system exhibits a high level of photocatalytic activity for H(2) generation, while the m-MoO(3)/TiO(2) system shows unique photochromism.
在氮气氛围下,将(NH4)2MoS4 溶于水和乙醇的混合溶液中,然后对 TiO2 进行紫外线照射,在 TiO2 表面生成了二硫化钼纳米颗粒(MoS2/TiO2)。随后将其在空气中于 773K 下加热,二硫化钼纳米颗粒转化为高度分散的六氧化钼物种(m-MoO3/TiO2)。在 HCOOH 水溶液中,MoS2/TiO2 体系对 H2 的生成表现出很高的光催化活性,而 m-MoO3/TiO2 体系则表现出独特的光致变色性。
