摘      要：Photoelectrochemical(PEC)water splitting is considered as an ideal technology to produce *** carrier migration is one of the most important roles in the whole process of PEC water *** includes bulk transfer inside of the photoelectrode and the exchange at the solid-liquid *** energy barriers during the migration process lead to the dramatic recombination of photogenerated hot carrier and the reducing of their redox ***,an applied bias voltage should be provided to overcome these energy barriers,which brings the additional loss of *** researches indicate that some methods for the regulation of photogenerated hot carrier,such as p-n junction,unique transfer nanochannel,tandem nanostructure and Z-Scheme transfer structure et al.,show great potential to achieve high-efficient PEC water overall splitting without any applied bias *** to now,many reviews have summarized and analyzed the methods to enhance the PEC or photocatalysis water splitting from the perspectives of materials,nanostructures and surface modification ***,few of them focus on the topic of photogenerated carrier transfer regulation,which is an important and urgent developing *** this reason,this review focuses on the regulation of photogenerated carriers generated by the photoelectrodes and summarizes different advanced methods for photogenerated carrier regulation developed in recent *** comments and outlooks are also provided at the end of this review.
