WebMar 11, 2024 · An orbital-selective Mott phase (OSMP) has been extensively discussed as anchoring the orbital-selective correlation phenomena in this regime. Motivated by … WebThrough gradient orbital coupling, the induced spin-up hole in Co 3d states endows the Er-O-Co unit active site with a spin-selective coupling channel for electron transition. This favors the decrease of the energy gap in the potential-limiting step, thus achieving a high theoretical limiting potential of 0.77 V RHE for the Er 2 O 3-Co.
