The conversion of solar energy to chemicals and the storage of this energy is one of the most promising routes to realizing a “carbon zero” society, for which particulate photocatalytic water splitting to produce hydrogen has been considered to be a clean potential route. For this purpose, many d⁰ and d¹⁰ metal-based nitrogen-incorporated oxide (including nitrogen-doped oxide and oxynitride) semiconductor photocatalysts have been developed as good candidates to harvest major visible regions of solar light and to exhibit suitable energy levels to drive water splitting. Compared to the oxide-type photocatalysts, valence bands of the nitrogen-incorporated oxide can be upshifted in consideration of the lower electronegativity of nitrogen atoms concerning the oxygen atoms.

调节氮结合氧化物光催化剂促进水分解的策略和方法

将太阳能转化为化学物质并储存这种能量是实现“零碳”社会的最有希望的途径之一，为此，颗粒光催化水分解制氢被认为是一种清洁的潜在途径。为此，已开发出许多 d ⁰和 d ¹⁰金属基掺氮氧化物（包括氮掺杂氧化物和氮氧化物）半导体光催化剂，作为收集太阳光主要可见区域并表现出合适的能级以驱动水分解。与氧化物型光催化剂相比，考虑到氮原子相对于氧原子的较低电负性，掺氮氧化物的价带可以上移。
