摘      要：Photocatalytic overall water splitting(OWS)for H2 and O2 evolution with a 2:1 stoichiometric ratio is one of the most promising ways to convert solar energy into chemical one,but it confronts huge challenges in consideration of the uphill water oxidation with four-electron transfer[1].During the past half century,great efforts have been made to the inorganic semiconductors-based photocatalysts,and to date the maximal apparent quantum efficiency(AQE)of OWS under ultra violet(UV)light has reached over 95%,as high as that of natural photosynthesis[2].Comparatively,however,the research on water splitting using conjugated polymers or hybrid metal-organic frameworks(MOFs)for photocatalysts is still in the infancy stage,and the achievement of OWS on them is tremendously limited because of additional challenges in addressing their poor charge separation and photochemical stability[3,4].
