N2 - Photocatalytic transfer hydrogenation (PCTH) relies on solar energy to drive liquid hydrogen source for the hydrogenation reaction of chemicals, possessing green chemical characteristics and high atomic economy. PCTH with liquid hydrogen source greatly improves the selectivity of hydrogenation and avoids safety issues arising from the use of molecular hydrogen. To address the limitation of the photocatalytic activity of the PCTH process, modulation strategies for internal electric field (IEF) within heterojunctions have been investigated and summarized in this article, such as fermi level regulation, interface interaction force, electronic mediator and piezoelectric effect, etc. In addition, this work reviewed the progress of PCTH technology and illustrated the development prospect of IEF within heterojunction in enhancing the performance of PCTH process, then prospected the future development direction of PCTH technology. The main purpose of this article was to summarize IEF modulation strategy in heterojunction photocatalysts and guide their application in PCTH to obtain better photocatalytic hydrogenation efficiency.
