Inspired by natural photosynthesis, harnessing the wide range of solar energy and utilizing appropriate semiconductor-based catalysts to convert carbon dioxide into beneficial species, for example, CO, CH4 , HCOOH, CH3 COH have been shown be a sustainable more environmentally friendly approach. Graphitic nitride (g-C3 N4 ) has regarded as highly effective photocatalyst CO2 reduction reaction, owing its cost-effectiveness, high thermal chemical stability, visible light absorption capability, low toxicity. However, weaker electrical conductivity, fast recombination rate, smaller window, reduced surface area make this catalytic material unsuitable commercial photocatalytic applications. Therefore, certain procedures, including elemental doping, structural modulation, functional group adjustment g-C3 addition metal complex motif, others, may used improve activity towards reduction. This review investigated scientific community's perspectives on synthetic pathways optimization approaches increase selectivity efficiency -based hybrid structures, well their benefits drawbacks Finally, concludes comparative discussion presents promising picture future scope improvements.
