The mechanism for CO₂ reduction over Fe-modified Cu(100) surfaces with thermodynamics and kinetics: a DFT study.

ABSTRACT: The adsorption, activation and reduction of CO₂ over Fe _x /Cu(100) (x = 1-9) surfaces were examined by density functional theory. The most stable structure of CO₂ adsorption on the Fe _x /Cu(100) surface was realized. The electronic structure analysis showed that the doped Fe improved the adsorption, activation and reduction of CO₂ on the pure Cu(100) surface. From the perspective of thermodynamics and kinetics, the Fe₄/Cu(100) surface acted as a potential catalyst to decompose CO₂ into CO with a barrier of 32.8 kJ mol^-1. Meanwhile, the first principle molecular dynamics (FPMD) analysis indicated that the decomposition of the C-O1 bond of CO₂ on the Fe₄/Cu(100)
