“…As an alternative to TiO₂, ZnO-based catalysts offer advantages such as higher electron mobility, lower production costs, versatile synthesis and improved UV absorption, resulting in improved quantum efficiency and superior photocatalytic kinetics. 2,7,8 Furthermore, the abundance, affordability and environmental friendliness of ZnO further increase its appeal. 9,10 However, its limited water splitting efficiency, particularly in the UV range where only a small fraction of solar radiation is present hinders its full potential.…”
