“…From the aspect of light absorption, narrow bandgap semiconductors such as Cu 2 (OH)PO 4 , Cu 2 S, Ag 2 S, and BiWO 6 with NIR response are promising to achieve full spectrum absorption. Unfortunately, narrow bandgap semiconductors suffer from low carrier separation efficiency and short carrier lifetime due to the limitation of Coulombic interactions between electrons and holes, limiting the light utilization efficiency. , Very recently, low-dimensional heterostructures including 0D/2D, 1D/2D, and 2D/2D systems , have gained popularity due to the short-range interfacial interaction of two low-dimensional materials, which can promote electronic coupling and electron transfer. Among them, the 0D/2D heterostructure photocatalysts show excellent catalytic activities compared to their counterpart particles with a large size and broad size distribution. , For example, it was recently proven that the PbS@CdS@ZnS/g-C 3 N 4 0D/2D photocatalysts show broadband activity under UV, vis, and NIR light irradiation because the strong interaction yields efficient charge separation and transfer between them …”
