InVO_4的禁带宽度约为2.0eV，是一种新型的可见光响应光催化剂。该光催化剂对可见光在600 nm以下的较宽波长范围内均表现出活性。虽然天然光催化剂在可见光照射下（λ> 420 nm）可以从纯水中放出H-2，但负载NiO作为助催化剂的光催化活性显著提高。结合最近报道的4d和5d过渡金属光催化剂InNbO（4）和InTaO 4，讨论了该化合物的晶体结构和电子结构与光催化性能的关系。(C)出版社：Elsevier Science B. V.
InVO4, with band gap of about 2.0 eV, was found to be a new visible light responding photocatalyst for water decomposition. The photocatalyst showed activity to visible light in a wide wavelength range up to 600 nm. Although the native photocatalyst could evolve H-2 from pure water under visible light irradiation (lambda > 420 nm), the photocatalytic activity increases significantly by loading NiO as a co-catalyst. Correlation of the photocatalytic properties with crystal and electronic structure of the compound is discussed in connection with the recently reported 4d and 5d transition metal photocatalysts lnNbO(4) and InTaO4.
