Özet
Hydrogen technologies are expected to replace fossil fuels, which currently meet a large portion of our energy needs. In this context, research on efficient hydrogen production is rapidly advancing, and water splitting methods are emerging as an environmentally friendly and sustainable alternative. Extensive research is available in the literature on electrocatalysts designed to minimize energy consumption and maximize process efficiency. The exceptionally superior properties of graphene derivatives, such as high surface area, conductivity, structural flexibility, and thermal and mechanical properties, have led to their widespread use in hydrogen production processes from water electrolysis. Furthermore, numerous studies have been published in the literature on electrocatalysts whose performance is enhanced by methods such as doping and metal integration, thanks to graphene’s modifiable chemical structure. Derivatives can be presented as graphene-based electrocatalysts, heteroatom-doped metal-free graphene electrocatalysts, precious metal-free transition metal graphene electrocatalysts, and precious metal graphene electrocatalysts. Our review reveals through a critical literature review that electrocatalysts produced from graphene derivatives in recent years may offer effective solutions to challenges such as low stability and high overpotentials in hydrogen evolution reactions (HER) and may also be important for future research aiming to increase efficiency and reduce costs.
