RHfON perovskites with R = La, Nd and Sm show a GdFeO-type structure and are semiconductors with band gaps of 3.35, 3.40 and 2.85 eV and relative dielectric constants of 30, 16 and 28 respectively. These compounds have adequate reduction and oxidation potentials to conduct the overall water splitting reaction, and the analogous perovskite LaZrON with a band gap of 2.8 eV shows photocatalytic activity under visible light irradiation for O evolution.
R为La、Nd和Sm的RHfON钙钛矿呈现出GdFeO型结构，是带隙分别为3.35、3.40和2.85 eV且相对介电常数分别为30、16和28的半导体。这些化合物具有足够的还原和氧化电位来进行整体水分解反应，且带隙为2.8 eV的类似钙钛矿LaZrON在可见光照射下对析氧显示出光催化活性。
