Efficient C-ZnS/ZnMoO@MoS and C-ZnS/MoS nanocomposite photocatalysts, using ZIF-8 derived C-ZnO as a precursor were successfully synthesized using a simple one-pot procedure. This is the first application that involves transforming ZIF-8 into C-ZnMoO for photocatalysis. The C-ZnS/ZnMoO@MoS and C-ZnS/MoS heterostructures were characterized by X-ray diffraction, UV-vis, X-ray photoelectron spectroscopy, electrochemical impedance spectroscopy, photocurrent measurements, scanning electron microscopy and transmission electron microscopy.

Here, a series of C-doped ZnO materials decorated with Au nanoparticles (Au/C-ZnO) were constructed controlled pyrolysis of ZIF-8 adsorbing different amounts of HAuCl·4HO. In this pyrolysis process, ZIF-8 was transformed into C-doped ZnO according to the EDX and XPS analysis.
