Abstract Environmentally benign hydrogen production via photochemical and photoelectrochemical processes by water splitting using carbon-based nanomaterials utilizes sunlight as the source of energy. Owing to their large surface area, pore volume, chemical and thermal stability, and favorable morphology, the carbon-based nanomaterials are quite effective in photocatalytic water splitting. The present review elucidates the photocatalytic nature of carbon materials such as graphene, graphene oxide, carbon nanotubes, graphitic carbon nitride, and fullerenes as they have the tendency to narrow the band gap, allocate electrons, and act as semiconductors, co-catalysts, photosensitizers, and support materials. The production methods, advantages as well as shortcomings of carbon-based materials and their applications in hydrogen production are critically discussed.
