摘要：Electrocatalytic (Figuer Presented) reduction of carbon dioxide (CO2) to carbon monoxide (CO) is an effective strategy to achieve carbon neutrality. High selective and low-cost catalysts for the electrocatalytic reduction of CO2 have received increasing attention. In contrast to the conventional tube furnace method, the high-temperature shock (HTS) method enables ultrafast thermal processing, superior atomic efficiency, and a streamlined synthesis protocol, offering a simplified method for the preparation of high-performance single-atom catalysts (SACs). The reports have shown that nickel-based SACs can be synthesized quickly and conveniently using the HTS method, making their application in CO2 reduction reactions (CO2RR) a viable and promising avenue for further exploration. In this study, the effect of heating temperature, metal loading and different nitrogen (N) sources on the catalyst morphology, coordination environment and electrocatalytic performance were investigated. Under optimal conditions, 0.05Ni-DCD-C-1050 showed excellent performance in reducing CO2 to CO, with CO selectivity close to 100% (?0.7 to ?1.0 V vs RHE) and current density as high as 130 mA/cm2 (?1.1 V vs RHE) in a flow cell under alkaline environment. ? 2025 Science Press.
