主　　题：graphitic carbon nitride heterojunctions nanoarrays photoelectrochemical water splitting 

摘      要：Photoelectrochemical(PEC)water splitting is recognized as a sustainable strategy for hydrogen generation due to its abundant hydrogen source,utilization of inexhaustible solar energy,high-purity product,and environment-friendly *** actualize a practical PEC water splitting,it is paramount to develop efficient,stable,safe,and low-cost photoelectrode ***,graphitic carbon nitride(g-C3N4)has aroused a great interest in the new generation photoelectrode materials because of its unique features,such as suitable band structure for water splitting,a certain range of visible light absorption,nontoxicity,and good *** inherent defects of g-C3N4,however,seriously impair further improvement on PEC performance,including low electronic conductivity,high recombination rate of photogenerated charges,and limited visible light absorption at long wavelength *** of g-C3N4-based nanosized heteroarrays as photoelectrodes has been regarded as a promising strategy to circumvent these inherent limitations and achieve the high-performance PEC water splitting due to the accelerated exciton separation and the reduced combination of photogenerated electrons/***,we summarize in detail the latest progress of g-C3N4-based nanosized heteroarrays in PEC water-splitting ***,the unique advantages of this type of photoelectrodes,including the highly ordered nanoarray architectures and the heterojunctions,are ***,different g-C3N4-based nanosized heteroarrays are comprehensively discussed,in terms of their fabrication methods,PEC capacities,and mechanisms,*** conclude,the key challenges and possible solutions for future development on g-C3N4-based nanosized heteroarray photoelectrodes are discussed.
