Synergistic Chemisorbing and Electronic Effects for Efficient CO<sub>2</sub> Reduction Using Cysteamine-Functionalized Gold Nanoparticles Zhijiang Wang Kun Sun Caiyun Liang Lina Wu Zhuangzhuang Niu Jianmin Gao 10.1021/acsaem.8b01699.s001 https://acs.figshare.com/articles/journal_contribution/Synergistic_Chemisorbing_and_Electronic_Effects_for_Efficient_CO_sub_2_sub_Reduction_Using_Cysteamine-Functionalized_Gold_Nanoparticles/7525058 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. 2018-12-24 00:00:00 CO 2 reduction NH Cysteamine-Functionalized Gold Nanoparticles NP chemisorbing CO 2 CA Efficient CO 2 Reduction mass activity carbon monoxide dehydrogenase Electronic
