Abstract

Aiming at demonstrating the highly-efficient wastewater treatment via photocatalytic hydrogen production, the nickel hydroxide-anchored biomass activated carbon (NH-AC) nanocomposites were synthesized through the facile sol-gel method followed by the ultrasonication process. The NH-AC nanocomposites exhibited an aggregated nanostructure with the large surface area of 75.02 m²/g. For the sulphide wastewater treatment, the nanocomposites showed the enhanced hydrogen production rate of 420 mL/h. Such a superb photocatalytic reaction for NH-AC can be ascribed to the synergic effects from both the high porosity of nickel hydroxide and the high electrical conductivity of activated carbon. These results depict that the NH-AC nanocomposites possess a great potential for photocatalytic hydrogen production from the wastewater.
