To enhance the quality of the environment, a lot of studies have been done on carbonaceous materials to develop different architectures and qualities. The development and importance of carbonaceous photocatalysts is briefly highlighted in this chapter, which also includes different semiconductors based on activated carbon, carbon nanotubes, carbon dots, fullerene, graphene, aerogels and carbon sponges, etc. In the present chapter, we have considered two types of strategies to discuss the entitled topic, one is a carbon-based catalyst, and the second is carbonaceous material with other metal composites to enhance the activity. Various difficulties with a metal catalyst, such as limited light adsorption capacity, large band gap energy, and insufficient physicochemical stability, continue to severely restrict photocatalysts for practical uses. To get rid of this, some unique catalysts based on carbon materials have been designed and inserted into a photocatalytic system to enhance activity. They are found to be ideal for various types of applications ranging from the field of renewable energy to waste water management and treatment, thanks to the synergistic combination of metal nanoparticles and carbonaceous nanostructures. Carbon-based metal nanostructures are much essential to dissolve a variety of colorful and colorless hazardous contaminants, such as organic dye, NOXelimination, water splitting, etc., when they are subjected to visible light. © 2023 Scrivener Publishing LLC.
