ZnInSe nanoparticles photocatalyst for efficient solar fuel production.

Selecting a suitable photocatalyst to establish the Z-scheme heterojunction which is accompanied by effective photogenerated hole and electron separation, is one of the advantageous strategies for efficient photocatalytic solar energy conversion. Therefore, we prepared a ZnInSe nanoparticles photocatalyst to build a double Z-scheme heterojunction with mixed-phase TiO nanofibers, boosting photocatalytic solar fuel preparation. The result of X-ray photoelectron spectroscopy confirmed the existence of interfacial chemical bonds and internal electric fields.
