Inspired by the architectural
feature of the natural enzyme of carbon monoxide dehydrogenase, cysteamine-capped
Au nanoparticles (CA–Au NPs) are investigated with remarkable
mass activity for CO<sub>2</sub> reduction. CA–Au NPs exhibit
exclusive CO selectivity, low onset overpotential, and a 110-fold
enhancement in mass activity compared with ligand-free Au NPs. Electronic
structure and in situ spectroscopy analyses indicate that increased
activity is due to the electronic effect derived from thiolate anchoring
on the surface and chemisorbing CO<sub>2</sub> and intermediates by
terminal -NH<sub>2</sub> functional groups. Our study provides the
basis for fabricating effective catalysts for CO<sub>2</sub> reduction.
