Sustainable valorization of industrial and solid wastes by utilizing them as feedstock to generate H2 via the photocatalytic reforming (PR) process holds great promise. It can also be an effective method to treat solid waste that otherwise would require tedious and expensive processes. This approach has the potential to offer energy solutions and form value-added chemicals. In this direction, developing photocatalysts and tuning their properties play an essential role in advancing the H2 generation efficiency. This Review article explores the application of 2D photocatalysts to generate H2 via PR of industrial waste (H2S) and solid waste, such as plastic and biomass. Despite having favorable optoelectronic properties, 2D photocatalysts are not widely employed for the PR process. The latest progress in employing 2D photocatalysts to realize efficient H2 evolution from biomass, plastic, and industrial waste such as H2S is detailed in this Review. A correlation between the properties of 2D photocatalysts with H2 evolution rate is discussed. We also emphasize understanding the mechanism involved in the PR process and the importance of 2D photocatalysts design. Such rational insight aids in further enhancing the H2 generation efficiency by effectively using solid/industrial waste as a feedstock.
