Abstract:
A carbon layer-supported FeNbO4 catalyst (FeNbO4/CLs) was developed for the carbon dioxide reduction reaction (CO2RR). Compared with unmodified FeNbO4, this catalyst promotes CH4 generation (yield reaching 152.9% of that of pristine FeNbO4), reduces CO yield to 90.0% of that of pristine FeNbO4, and maintains high operational stability. Characterization results confirm that the modification using carbon layers facilitates reaction intermediate formation, and first-principles calculations show that carbon layers reduce the overall reaction energy barrier and prevent *CHO intermediate poisoning of the catalyst surface.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
