Cover Story: This research presents results in hydrogen production using biomimetic catalysts based on Au@ZnO-graphene composites. The catalysts were prepared by incorporating gold nanoparticles and graphene on the surface of zinc oxide nanowires (ZnO NWs), zinc oxide nanoparticles (ZnO NPs), and commercial ZnO. The highest amount of hydrogen was reported by ZnO NWs, followed by ZnO NPs and finally commercial ZnO. The high photocatalytic activity of the catalysts is attributed, mainly, to the synergism between the different amount of gold and graphene incorporated, and the surface area of the composites.
