Notably, production of hydrogen and oxygen through photocatalytic water splitting process is very promising process for solar energy utilization. [ 12 ] 2D nanosheets have high specific surface area, abundant catalytic active sites, and shorter diffusion length of charge carriers, thus stimulating a wide range of interests in photocatalytic water splitting.
Photocatalytic water splitting typically relies on the internal electric field to achieve photogenerated charge separation. The spontaneous electric polarization of ferroelectrics could offer a strong internal electric field toward the photocatalytic water splitting process. Water Splitting The discovery of the photocatalytic splitting of water on TiO 2 electrodes by Fujishima and Honda in the early 1970s resulted in the beginning of a new era in photo-catalysis and prompted extensive research concerning solar energy conversion9),10). In their pioneering re-search, UV irradiation of a TiO 2 single-crystal electrode photocatalytic water splitting is to split water into H 2 and O 2 using a single visible-light-responsive photocatalyst (a one-step system). Sacrificial reagents are often employed to evaluate the photocatalytic activity for water splitting, because overall water splitting is a tough reaction. 2020-10-29 · The light-driven photocatalytic water splitting to produce hydrogen has become the most promising method for scientific research to obtain sustainable energy [5, 6]. Researchers from all the world had found a mount of semiconductor photocatalyst showing good photocatalytic activities for water splitting to produce hydrogen (H 2) [7,8,9].
