Artificial photosynthesis of H2O2using earth-abundant water and oxygen is a promising approach to achieve scalable and cost-effective solar fuel production. Recent studies on this topic have made significant progress, yet are mainly focused on using organic polymers. This set of photocatalysts is susce...
of half reactions,ie.,the oxygen reduction reaction(ORR)and water oxidation reaction(WOR),greatly restricts the efficiency of photocatalytic H2O2 production.In this highlight,we discuss the significant ad-vances in molecular engineering of carbon nitrides for H2O2 photosynthesis and the importanc...
The conversion of solar energy to chemical energy is a promising way of generating renewable energy. Hydrogen production by means of water splitting over semiconductor photocatalysts is a simple, cost-effective approach to large-scale solar hydrogen synt
It can be seen that, following the hydrothermal reaction, the red phosphorus microspheres formed a relatively uniform nano-flake structure. A high-resolution SEM image of the phosphorus nanosheets is shown in Fig. 3b; the phosphorus sheets clearly appear as a folded film. The morphology, mapping...
Graphitic carbon nitride based polymers, being metal-free, accessible, environmentally benign and sustainable, have been widely investigated for artificial photosynthesis in recent years for the photocatalytic splitting of water to produ... G Zhang,ZA Lan,X Wang - 《Chemical Science》 被引量: 10发表...

Converting solar energy into hydrogen (H2) by photocatalytic water splitting is a promising approach to simultaneously address the increasing energy demand and environmental issues. Half decade has passed since the discovery of photo-induced water splitting phenomenon on TiO2photoanode, while the solar to...

Metal–organic frameworks (MOFs) have been studied extensively in the hydrogen evolution reaction (HER) and the water oxidation reaction (WOR) with sacrificial reagents, but overall photocatalytic water splitting using MOFs has remained challenging, principally because of the fast recombination of photo-...
followed by a spontaneous chemical step that is driven faster at higher temperature, which reduces the anode back to its initial state by oxidizing water. This enables overall water splitting at average cell voltages of 1.44–1.60 V with nominal current densities of 10–200 mA cm−2...
