Hydrogen is a clean, green and sustainable energy and photocatalysis a better approach for hydrogen production from various wastewaters. It was aimed to evolve new hybrid solar-driven catalysts for photocatalytic hydrogen production from various wastewaters. Firstly, catalysts were synthesized. Their characterization study were performed and PL results show that the most promising catalyst was GLFO. The impacts of pH, catalyst loading and light over hydrogen production from SMS were investigated using all synthesized catalysts. The hybrid catalysts show higher efficiency. FFD was created to elucidate the impacts of reaction parameters and graphene content of catalyst had a major impact. To optimize the reaction parameters for all hybrid catalysts, an experimental matrix was created using BBD. The higher hydrogen amounts were observed using GLFO. The same experimental matrix was used to search the effects of reaction parameters over produced hydrogen amounts from sugar beet wastewater using all hybrid catalysts and the highest hydrogen production was observed using GLFO. The observed reaction followed first order reaction model based on TOC removal. Therefore, the degradation of organic pollutants in wastewater streams and hydrogen evolution could simultaneously be achieved. Same experimental matrix was also used for hydrogen evolution from DBU using all hybrid catalysts. Relatively lower hydrogen amounts were obtained so that it was also treated under subcritical conditions. FFD was created to search the impacts of reaction parameters and NaOH concentration and current density had an impact over DBU removal. Based on GC-MS results, the hazardous intermediates did not form during hydrothermal electrolysis.
