Tunable CO/H2 ratios of electrochemical reduction of CO2 through the Zn-Ln dual atomic catalysts.
Ontology highlight
ABSTRACT: Electrochemical reduction of CO2 (CO2RR) to value-added liquid fuels is a highly appealing solution for carbon-neutral recycling, especially to syngas (CO/H2). Current strategies suffer from poor faradaic efficiency (FE), selectivity, and controllability to the ratio of products. In this work, we have synthesized a series of single and dual atomic catalysts on the carbon nitride nanosheets. Adjusting the ratio of La and Zn atomic sites produces syngas with a wide range of CO/H2 ratios. Moreover, the ZnLa-1/CN electrocatalyst generates the syngas with a ratio of CO/H2 = 0.5 at a wide potential range, and the total FE of CO2RR reaches 80% with good stability. Density functional theory calculations have confirmed that the Zn and La affect
