| Abstract | Metal single-atom catalysts (SACs) supported on carbon mainly produce syngas in electrochemical CO reduction reaction (CORR), in comparison with the dominant H production on nanoparticles. However, it is a major challenge to prepare the carbon-supported SACs without the presence of nanoparticles using conventional pyrolysis. Here, we report the approach involving oxygen etching at 250 °C to produce MOF-derived nickel/carbon SAC (Ni@C-250A). The combination of oxygen etching with acid treatment completely removes the Ni nanoparticles, only showing the existence of single-atom Ni species. In CORR, the Ni@C-250A exhibits excellent faradaic efficiency (FE) of ∼ 100% for syngas production with the excellent stability for 360 min time-on-stream. In addition, the CO/H ratio can be adjusted in a wide range from 1.5:1 to 4.3:1. This approach involving oxygen etching offers a promising strategy to dominantly produce SACs used for CORR to generate syngas, which is an important platform feedstock for the utilization of carbon-based energy. |
