“…Recently, excellent review papers have been published on CN-based pCO2R catalysts and their applications in the environment and energy sectors [80][81][82][83][84][85][86]. However, to the best of our knowledge, no review paper entirely dedicated to Cu-CN-based catalysts for pCO2R, ECO2R, and pECO2R has been reported so far.…”

The processes of photocatalytic CO 2 reduction (pCO 2 R) and electrochemical CO 2 reduction (ECO 2 R) have attracted considerable interest owing to their high potential to address many environmental and energy-related issues. In this aspect, a single Cu atom decorated on a carbon nitride (CN) surface (Cu-CN) has gained increasing popularity because of its unique advantages, such as excellent atom utilization and ultrahigh catalytic activity. CN-particularly graphitic CN (g-C 3 N 4 )-is a photo-and electrocatalyst and used as an important support material for single Cu atom-based catalysts. These key functions of Cu-CN-based catalysts can improve the catalytic performance and stability in the pCO 2 R and ECO 2 R during the application process. In this review, we focus on Cu as a single metal atom decorated on CN for efficient photoelectrochemical CO 2 reduction (pECO 2 R), where ECO 2 R increases the electrocatalytic active area and promotes electron transfer, while pCO 2 R enhances the surface redox reaction by efficiently using photogenerated charges and offering integral activity as well as an active interface between Cu and CN. Interactions of single Cu atom-based photo-, electro-, and photoelectrochemical catalysts with g-C 3 N 4 are discussed. Moreover, for a deeper understanding of the history of the development of pCO 2 R and ECO 2 R, the basics of CO 2 reduction, including pCO 2 R and ECO 2 R over g-C 3 N 4 , as well as the structural composition, characterization, unique design, and mechanism of a single atom site are reviewed in detail. Finally, some future prospects and key challenges are discussed.

“…Furthermore, Li, Ca, and Ba metal depositions require more challenging conditions than Na or K. Carbon deposition is less difficult in Li, Ca, and Ba carbonates than in Na or K carbonates, as shown in Table 4. 34,60 Li 2 CO 3 conductivity is 6 S cm −1 , 2 times higher than Na 2 CO 3 and 3 times higher than K 2 CO 3 at their melting points. 74 Its higher conductivity lowers ohmic loss and thus enhances reactant or electron mass transfer.…”

“…23,[27][28][29][30] A variety of conversion methods, such as photochemical, biological, and hydrogen transformation pathways, are being developed for industrial applications. [31][32][33][34] The advantage of these methods is that they can obtain hydrocarbons and other marketable products (such as dimethyl carbonate, synthesis gas, carboxylic acids, methane, etc.) that are significantly more valuable than pure CO 2 .…”

“…[195,196] The later CO 2 hydrogenation reactions are exothermic, as seen from the negative values of their ΔH Value. [197] Correspondingly, CO 2 is famous for its chemical inertness, stability, and linearity; therefore, to bend or break the linear CO bond, a special photocatalyst and a significant amount of energy is required. For example, the ΔG to convert 1 mole of water through water splitting into H 2 and 1/2O 2 is 237.2 kJ mol −1 under STP.…”

A Comprehensive Review on Graphitic Carbon Nitride for Carbon Dioxide Photoreduction

Inspired by natural photosynthesis, harnessing the wide range of natural solar energy and utilizing appropriate semiconductor‐based catalysts to convert carbon dioxide into beneficial energy species, for example, CO, CH4, HCOOH, and CH3COH have been shown to be a sustainable and more environmentally friendly approach. Graphitic carbon nitride (g‐C3N4) has been regarded as a highly effective photocatalyst for the CO2 reduction reaction, owing to its cost‐effectiveness, high thermal and chemical stability, visible light absorption capability, and low toxicity. However, weaker electrical conductivity, fast recombination rate, smaller visible light absorption window, and reduced surface area make this catalytic material unsuitable for commercial photocatalytic applications. Therefore, certain procedures, including elemental doping, structural modulation, functional group adjustment of g‐C3N4, the addition of metal complex motif, and others, may be used to improve its photocatalytic activity towards effective CO2 reduction. This review has investigated the scientific community's perspectives on synthetic pathways and material optimization approaches used to increase the selectivity and efficiency of the g‐C3N4‐based hybrid structures, as well as their benefits and drawbacks on photocatalytic CO2 reduction. Finally, the review concludes a comparative discussion and presents a promising picture of the future scope of the improvements.
