The Cover Feature shows a comparison of Ti‐Fe 2 O 3 photoanodes modified with quasi‐Fe(salen) and Ru(salen) as cocatalysts, which enhance the photocurrent density of Ti‐Fe 2 O 3 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.
