Abstract:
Modulating the Pt d-band center via metal-semiconductor interaction on non-stoichiometric Bi2Te3 unlocks efficient C1 electrooxidation. The optimized catalyst shows mass activities of 11.0 A mgPt-1/12.7 A mgPt-1 for the FAOR/MOR, which are 22 and 9.8 times those of commercial Pt/C, respectively, and a CO-free complete oxidation direct pathway.

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.
CFT focuses on...
