Cover Story: Hydrogen energy has been great interest as the solution for the looming environmental crisis. The hydrogen energy can be produced through water splitting without any polluting byproducts, such as CO2. Owing to its low-cost, abundancy, and excellent catalytic properties, the carbon materials have shown great aspect towards the water splitting reactions. Especially, low-dimensional carbon-based materials, such as graphene, graphitic carbon nitride, and their derivatives, possess favorable catalytic properties and are engaged to employ in various water splitting systems. Furthermore, the light-absorbing capability of graphene oxides and graphene quantum dots have opened to the solar-induced method of hydrogen production. Therefore, carbon-based materials with their inspiring performances can effectually enhance the efficiency of water splitting systems for eco-friendly hydrogen production. View this paper.
