To design and synthesize a diversity of high- density SACs to improve selectivity and efficiency of CO2RR; by thermal pyrolysis of well- designed precursors or sequential atomic layer deposition.
We aim to develop a novel approach for the large scale production of stable mono- metal and bimetallic SACs with tunable metal loading, for the further optimisation of catalytic performance towards electrochemical CO2 reduction. To further expand the catalysts functionalities and optimize their catalytic efficiency, it is essential to invent new concepts for the design of novel multifunctional SACs, with diverse combinations of metal elements. Unfortunately, it remains a major challenge to synthesize the multifunctional SACs with different kinds of metal elements. We aim to synthesize these multi-functional SACs via thermal pyrolysis of well-designed precursors or sequential atomic layer deposition. We expect these SACs with bimetallic active sites will promote the formation of value-added product (beyond CO) in the electrochemical CO2 reduction.
