Abstract

Hydrogen is being considered as the green and renewable fuels in the near future to replace the high global energy demands on fossil fuels. In this work, the photocatalyst reduce graphene oxide (RGO) composited (ZnNi)(O,S) with different amount of RGO has been developed for photocatalytic hydrogen production. X-ray did not show any characteristic peak of RGO due to a little amount in nanocomposite catalyst. However, elemental mapping clearly exhibited the presence of carbon as the element constituent of RGO. Based on the EIS result, RGO could decrease the charge transfer resistance to let the photogenerated electrons-holes easily migrate on the surface of catalyst for executing oxidation and reduction reactions. The optimum amount of RGO was 5 mg to provide the highest hydrogen production rate of 8100 μmol/gh. The enhanced hydrogen production rate was investigated and explained in this paper.
