Abstract
The production of value-added chemicals from CO2 electroreduction, using renewable energy, provides an appealing route to achieve the goal of carbon neutrality. Challenges remain in designing and understanding of high-performance catalysts with restructuring behavior under electrochemical conditions. Here, the intrinsic performance enhancement of an Au-complex derived carbon nanotube-supported Au nanoclusters catalyst was demonstrated for CO2 reduction. This catalyst exhibited impressive activity for yielding CO in both H-cell and flow cell reactors. Experimental results revealed that the synthesis procedure via metal complex reconstructing on proper support induced charge transfer between Au nanoclusters and carbon nanotubes, forming a rather electron-rich state for Au active sites, which greatly contributed to the CO2 activation pathway.
