Surface engineering of graphitic carbon nitride polymers with cocatalysts for photocatalytic overall water splitting

摘要: Graphitic carbon nitride based polymers, being metal-free, accessible, environmentally benign and sustainable, have been widely investigated for artificial photosynthesis in recent years the photocatalytic splitting of water to produce hydrogen fuel. However, stoichiometric pure into H2 O2 with a molecular ratio 2 : 1 is far from easy, usually hindered by huge activation energy barrier sluggish surface redox reaction kinetics. Herein, we provide concise overview cocatalyst modified graphitic photocatalysts, our main focus on modulation We believe that timely review this promising but challenging research topic will certainly be beneficial general readers researchers order better understand property–activity relationship towards overall splitting, which could also trigger development new organic architectures through rational control chemistry.
