Recent advances in p-block metal chalcogenide electrocatalysts for high-efficiency CO2 reduction

Recent Progress in Electrochemical CO2 Reduction at Different Electrocatalyst Materials

“…However, the experimental potential of the reactions is higher than the thermodynamic one due to resistance to charge transfer and ohmic drop. To ensure an efficient CO 2 catalytic reaction, it is important to promote both the cathodic half-reaction and the anodic halfreaction (OER), making use of a highly active catalyst and creating reaction conditions that minimize resistance ohmic, allow adequate mass transport [31], and kinetically inhibit the formation of H 2 as much as possible, while at the same time promoting the reduction of CO 2 to increase the production of desired products [28].…”

“…In the literature, researchers [31][32][33] have emphasized that the main challenge in CO 2 RE is the manufacture of electrocatalysts with high conversion efficiency, high selectivity of the product formed, and low overpotential [15,25]. Thus, this theme continues to be widely discussed, with investigative studies related to overpotential parameters, current density (j), faradaic efficiency, and catalyst stability [25,34,35].…”

“…Ren and collaborators demonstrated the mechanisms of ethanol and ethylene formation via the electrochemical reduction of CO 2 . Equations ( 30) and (31) present the global reactions of ethylene and ethanol, respectively [98].…”

Graphene quantum dot-mediated anchoring of highly dispersed bismuth nanoparticles on porous graphene for enhanced electrocatalytic CO2reduction to formate

“…On the other hand, within the reaction pathway, the hydrogen evolution reaction (HER) in an aqueous electrolyte acts as a competing side reaction, making it challenging for the CO 2 RR to generate the desired product. [11][12][13][14][15][16][17] Hence, there is a pressing demand to develop electrocatalysts with high efficiency for the CO 2 RR that can enhance both the reaction rate and the selectivity toward the target product.…”

NAD(P)H-Inspired CO2 Reduction Based on Organohydrides

“…Many efforts have already been devoted to developing catalytic systems for accomplishing the CO 2 R, including photocatalysis, − electrocatalysis, − thermal catalysis, − and enzyme catalysis . However, most of the catalysts in these systems consisted of earth-abundant metals or even noble metals.…”
