| description | This article describes the effective synthesis of colloidal SnO<sub>2</sub> quantum dots and ZnWO<sub>4</sub> nanorods using wet chemical synthesis and hydrothermal synthesis, respectively. The resulting ZnWO<sub>4</sub>-SnO<sub>2</sub> core–shell nanorod heterostructure is then made, and its structural, optical, and morphological properties are assessed using XRD, SEM, TEM, and DRS. The heterojunction’s structural confinement increases the exposure of its reactive sites, and its electronic confinement promotes its redox activity. The heterostructure subsequently exhibits a smaller bandgap and better light-harvesting capabilities, resulting in increased photoelectrochemical performance. The heterostructure of core–shell nanorods shows promise for usage in a range of optoelectronic devices and effective solar energy conversion. |
