Abstract	Cost-effective heteroatom-doped porous carbons are consideredpromisingelectrocatalysts for CO2 reduction reaction (CO2RR). Traditionally porous carbons with N doping or N/X codoping (Xdenotes the second type of heteroatom) have been widely studied, leavingternary doping a much less studied yet exciting topic to be explored.Herein, a series of electrocatalysts based on metal-free Se, B, andN ternary-doped porous carbons (termed “SeBN-Cs”) weresynthesized and tested as metal-free electrocatalysts in CO2RR. Our study indicates that the major product of CO2RRon the SeBN-C electrocatalysts was CO with a small fraction (<5%)of H2 as the byproduct. The optimal electrocatalyst sampleSeBN-C-1100 prepared at 1100 °C exhibits a high CO selectivitywith a Faradaic efficiency of CO reaching 95.2%. After 10 h of continuouselectrolysis operation, the Faradaic efficiency and the current densityare maintained high at 97.6 and 84.7% of the initial values, respectively,indicative of a long-term operational stability. This study providesan excellent reference to deepen our understanding of the propertiesand functions of multi-heteroatom-doped porous carbon electrocatalystsin CO2RR.
