本文首次报道了分散有RuO 2纳米颗粒的氮化锗β-Ge 3 N4作为非氧化物光催化剂催化H2O化学计量分解为H2和O2的实例。在过去30年中，所有成功开发的用于整体水分解的光催化剂都是基于金属氧化物。因此，非氧化物光催化剂的发现，如氮化物和氮氧化物，实现相同的功能，预计将刺激对非氧化物光催化剂的研究。因此，可以预期在可见光驱动的ZnO的开发中取得进展的新机会，因为与相应的金属氧化物相比，金属氮化物的更高的价带位置提供了更窄的带隙，这适合于可见光活性。
Germanium nitride β-Ge3N4dispersed with RuO2nanoparticles is presented as the first example of a non-oxide photocatalyst for the stoichiometric decomposition of H2O into H2and O2. All of the successful photocatalysts developed for overall water splitting over the past 30 years have been based on oxides of metals. The discovery of a non-oxide photocatalyst, such as nitrides and oxynitrides, achieving the same function is therefore expected to stimulate research on non-oxide photocatalysts. New opportunities for progress in the development of visible light-driven photocatalysis can thus be expected, as the higher valence band positions of metal nitrides compared to the corresponding metal oxides provide narrower band gaps, which are suitable for visible light activity.
