Abstract

- Exploring high-efficient oxygen evolution reaction (OER) catalysts is critical for producing clean H-2 fuel through water splitting. Co and P involved Co-Pi and cobalt phosphide OER catalysts attracted tremendous attention, while limited report on cobalt phosphite as an OER catalyst. Herein, a novel cobalt phosphite nanowires with microporous 1D channel have been succsessfully discovered with remarkable catalytic performance of a low overpotential of (similar to)340 mV and Tafel slope of 60 mV dec(-1) at 10 mA cm(-2) at pH 14. Through comprehensive structural characterization, the effective species has been clearly illustrated to be the in-situ formed heterostructural Co-11(HPO3)(8)(OH)(6)/Co-11(PO3)(8)O-6 core-shell structure nanowires. This work fills the gap for exploring high efficient cobalt phosphites OER catalysts under akaline condition and paves the way for exploring novel high efficiency waster splitting catalysts.
