The Cover Feature shows a comparison of Ti-Fe₂O₃ photoanodes modified with quasi-Fe(salen) and Ru(salen) as cocatalysts, which enhance the photocurrent density of Ti-Fe₂O₃ photoanode by 1.5 and 1.7 times, respectively. As a cocatalyst, the quasi-Fe(salen) clearly increases the conductivity and reaction kinetics at the liquid–semiconductor interface, while the quasi-Ru(salen) offers more metal sites to the electrolyte, which act as the new reaction sites. Both quasi-Fe(salen) and Ru(salen) are effective as cocatalysts for photoelectrochemical water oxidation reaction with different advantages. More information can be found in the Full Paper by R. Wang et al.

封面内容：准分子助催化剂对掺钛赤铁矿光阳极的改性：非贵金属与贵金属改善机理的比较（ChemSusChem 10/2021）

封面功能显示的Ti-Fe的比较₂ ö ₃具有准的Fe（沙仑）和Ru（沙仑）作为助催化剂，其增强的Ti-Fe的光电流密度改性光阳极₂ ö ₃由分别为1.5和1.7倍，光电阳极。作为助催化剂，准Fe（salen）明显增加了液-半导体界面处的电导率和反应动力学，而准Ru（salen）为电解质提供了更多的金属位点，它们是新的反应位点。准Fe（salen）和Ru（salen）都可以作为光电化学水氧化反应的助催化剂，但具有不同的优势。更多信息可以在R. Wang等人的论文全文中找到。
