“…C 2 H 2 À TPD was used to verify the research results of acetylene adsorption performance of catalysts before and after cyclic voltammetry treatment. Fu et al [56] used CO 2 -TPD to test the prepared SACs CoÀ CN and the carrier g-C 3 N 4 , and further verified the adsorption behavior of the carrier g-C 3 N 4 and 1 %CoÀ CN for CO 2 . Both g-C 3 N 4 and 1 %CoÀ CN have obvious desorption peaks at 120 °C, which are related to the physical/chemical adsorption of CO 2 .…”

Single-atom catalysts (SACs) have attracted extensive attention since their emergence. During the single-atomic catalytic process, the "active center" exists in the form of atomical monodispersion, with nearly 100 % utilization of metal atoms. Uniform and atomically dispersed catalytic centers give SACs pronounced reaction activity and chemical selectivity. Here, we review the development processes, synthetic strategies, charac-terization methods, and applications of SACs in CO 2 reductive upgrading. Also, a comparison of SACs with conventional heterogeneous catalysts in catalytic CO 2 reduction is made and discussed. SACs have built a bridge between homogeneous and heterogeneous catalysis and have the advantages of both, showing a broad prospect in the field of catalysis.

“…Additionally, the energy barrier of the RDS on Co‐g‐C 3 N 4, which was the CO desorption step (1.15 eV), was lower compared to g‐C 3 N 4 (CO 2 * hydrogenation step with an energy barrier of 1.63 eV), indicating the enhanced activation of CO 2 due to its interaction with the Co single atom sites. The improved adsorption and activation behavior translated to a superb CO production rate of 94.9 μmol g −1 h −1 , while pure g‐C 3 N 4 had a yield of 0.25 μmol g −1 h −1 under the same conditions 196 …”

CO2 capture and conversion has been prospected as an auspicious technology to simultaneously tackle the rise in global CO2 emission and produce value‐added fuels with the goal of accomplishing carbon neutrality. A sustainable route to achieve this is via the utilization of solar energy, thereby harnessing the abundant and nonexhaustive resource to shift our reliance away from rapidly depleting fossil fuels. Graphitic carbon nitride (g‐C3N4) and its allotrope have earned its rank as a fascinating metal‐free photocatalyst due to its superior stability, high surface‐area‐to‐volume ratio, and tunable surface engineering. By leveraging these properties, robust carbon nitride‐based nanostructures are engineered for photocatalytic CO2 conversion to energy‐rich C1C2 product, which is indispensable in the chemical industry. Thus, this review presents the latest panorama of experimental and computational research on tuning the local electronic, surface chemical coordination environment, charge dynamics and optical properties of low‐dimensional carbon nitride and its allotropes toward highly selective and efficient CO2 photoconversion. To name a few, structural engineering, point‐defect engineering, heterojunction construction, and cocatalyst loading. To advance this frontier, critical insights are elucidated to establish the structure‐performance relationship and unravel primary factors dictating the selectivity of C1C2 molecules from CO2 reduction. External‐field assisted photocatalysis such as with electric (photoelectro‐) and heat (photothermal) is discussed to uncover the synergistic contributions that drive the development in photochemistry. Last, future challenges and prospects are outlined for the potential application of solar‐driven CO2 conversion, along with the scale‐up strategy from the economic viewpoint toward the rational development of high‐efficiency carbon nitride catalysts.

“…Cobalt nitrides have proved beneficial for CO 2 RR because they offer more surface base sites of adsorption of CO 2 and the generation of more active sites [ 140 , 141 , 142 , 143 , 144 , 145 , 146 ]. Peng et al reported the highly efficient CO 2 RR cobalt nitride catalysts (700-Co 5.47 N/C) in an aqueous electrolyte.…”

Electrochemical CO2 reduction reaction (CO2RR) provides a promising approach to curbing harmful emissions contributing to global warming. However, several challenges hinder the commercialization of this technology, including high overpotentials, electrode instability, and low Faradic efficiencies of desirable products. Several materials have been developed to overcome these challenges. This mini-review discusses the recent performance of various cobalt (Co) electrocatalysts, including Co-single atom, Co-multi metals, Co-complexes, Co-based metal–organic frameworks (MOFs), Co-based covalent organic frameworks (COFs), Co-nitrides, and Co-oxides. These materials are reviewed with respect to their stability of facilitating CO2 conversion to valuable products, and a summary of the current literature is highlighted, along with future perspectives for the development of efficient CO2RR.
