Constructing artificial mimic-enzyme catalysts for carbon dioxide electroreduction
文献摘要：
Natural bio-enzyme catalysts usually exhibit unexpected performances for many significant reactions,which are worthy of reference.Here we report artificial metal-sulfur-carbon (M-S-C) mimic-enzyme catalysts based on bionic design.The catalysts combine metal centers and functional ligands,which realize the universal fabrication of phase and adjustable dimension.The synthesized catalysts inherit the highly active and selective feature of bio-enzyme catalysts.When directly used for carbon dioxide electroreduction reaction,the Sn-S-C catalyst exhibits high selectivity for formate (Faradaic efficiency ＞95％),as well as a continuous stability over 120 h at a high current density of 740 mAcm-2,greatly outperforming the reported catalysts for formate formation.The catalytic sites and pathways are probed with in-situ Fourier transform infrared (FTIR) spectra,in-situ Raman spectra and synchrotron-radiation X-ray photoelectron spectra.These results break the inherent conundrum that it is impossible to simultaneously realize activity and durability under high selectivity.Our findings offer a versatile strategy to inherit from nature and integrate different components,thus designing efficient catalysts for various challenging reactions and energy conversions via a natural sustainable way.
