    • MV2+ is only used in alkaline condition to ensure its adsorption on TiO2 surface.48 In addition, the produced MV+ has a wide absorption around 600 nm, overlapping with the reported hole absorption around 475 nm. Hereby MV2+ is not a suitable electron scavenger in gaseous environment and neutral solution. Tetranitromethane and Ce(SO4)2 have low solubility in water and the latter has optical absorption around 450 nm, so they are not very suitable as electron scavengers in aqueous solution yet. Furthermore, MV 2+ and tetranitromethane are very toxic to the environment. Pt is used to select as a cocatalyst to accelerate H2 production partially because of its ability of trapping/separating electrons.21 Ag, also is a common electron scavenger
