“…The Pd-MXene electrode had higher CO 2 RR and stability than any other electrode, making it a superior electrode for producing CH 3 OH under optimal conditions. Accordingly, Pd-MXene electrodes are highly competitive with other electrode materials that have been recently studied in terms of their ability to reduce CO 2 into selectively produced CH 3 OH, which includes the following materials: Cu 2−x Se(y) nanocatalysts, Ru polypyridyl carbene catalyst on N-doped porous carbon, transition metals supported on g-C 3 N 4 , transition metal oxides, boron phosphide nanoparticles, hierarchical Pd/SnO 2 nanosheets, Cu/Ti 3 C 2 Tx, metal-free B 2 S sheet, defectsrich Ni 3 S 2 -CNFs nanoheterostructures, etc., [27,30,[35][36][37][38][39][40][41]. The Pd-MXene was shown to be an effective candidate for reducing flue gases into fuels in order to control climate change.…”

Palladium nanoparticles (Pd NPs) have attracted considerable attention recently for their excellent catalytic properties in various catalysis reactions. However, Pd NPs have some drawbacks, including their high cost, susceptibility to deactivation, and the possibility of poisoning by intermediate products. Herein, Pd nanoparticles with an average diameter of 6.5 nm were successfully incorporated on electronically transparent 2D MXene (Ti3C2Tix) nanosheets (Pd-MXene) by microwave irradiation. Considering the synergetic effects of ultra-fine Pd NPs, together with the intrinsic properties of 2D MXene, the obtained Pd-MXene showed a specific surface area of 97.5 m2g−1 and multiple pore channels that enabled excellent electrocatalytic activity for the reduction of CO2. Further, the 2D Pd-MXene hybrid nanocatalyst enables selective electroreduction of CO2 into selective production of CH3OH in ambient conditions by multiple electron transfer. A detailed explanation of the CO2RR mechanism is presented, and the faradic efficiency (FE) of CH3OH is tuned by varying the cell potential. Recyclability studies were conducted to demonstrate the practical application of CO2 reduction into selective production of CH3OH. In this study, metal and MXene interfaces were created to achieve a highly selective electroreduction of CO2 into fuels and other value-added chemical products.

“…It was shown that negatively charged borophene could promote CO 2 molecule capture ( Figure 6F ). Sun et al adopted the metal-free B 2 S catalyst to convert CO 2 into CH 3 OH by DFT calculations ( Tang et al, 2020 ). The thermodynamic and kinetic energy barriers were −0.12 eV and 0.43 eV, respectively.…”

Excess of carbon dioxide (CO2) in the atmosphere poses a significant threat to the global climate. Therefore, the electrocatalytic carbon dioxide reduction reaction (CO2RR) is important to reduce the burden on the environment and provide possibilities for developing new energy sources. However, highly active and selective catalysts are needed to effectively catalyze product synthesis with high adhesion value. Single-atom catalysts (SACs) and double-atom catalysts (DACs) have attracted much attention in the field of electrocatalysis due to their high activity, strong selectivity, and high atomic utilization. This review summarized the research progress of electrocatalytic CO2RR related to different types of SACs and DACs. The emphasis was laid on the catalytic reaction mechanism of SACs and DACs using the theoretical calculation method. Furthermore, the influences of solvation and electrode potential were studied to simulate the real electrochemical environment to bridge the gap between experiments and computations. Finally, the current challenges and future development prospects were summarized and prospected for CO2RR to lay the foundation for the theoretical research of SACs and DACs in other aspects.
