Abstract The production of value‐added chemicals from CO 2 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 CO 2 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 CO 2 activation pathway.
