Bifunctional Z-Scheme Ag/AgVO/g-CN photocatalysts for expired ciprofloxacin degradation and hydrogen production from natural rainwater without using scavengers.

To maximize the employment of sustainable solar energy in treating the recalcitrant pollutant and hydrogen energy production, the development of a highly efficient photocatalyst is desirable. Herein, a Z-scheme Ag/AgVO/g-CN photocatalyst was synthesized via a wet-impregnation method. The amount of Ag/AgVO deposited onto g-CN has a significant effect on the photocharge carrier separation and migration of the as-developed Z-scheme photocatalyst.
