Oxygen-doped hollow, porous NiCoP nanocages derived from Ni-Co prussian blue analogs for oxygen evolution

Chem Commun (Camb). 2021 Jul 27. doi: 10.1039/d1cc00535a. Online ahead of print.ABSTRACTAn oxygen-doped, hollow, porous NiCoP nanocage (O-NiCoP Cages) electrocatalyst was synthesized derived from Ni-Co Prussian blue analogs. O-NiCoP Cages exhibited an overpotential of 310 mV at 10 mA cm-2 and a Tafel slope of 84 mV dec-1, significantly higher than that of undoped NiCoP nanocages, and also better than that of RuO2 and several reported phosphide electrocatalysts. This work provides a new strategy for the design of highly efficient oxygen evolution reaction (OER) electrocatalysts based on hollow, nanostructured and heteroatom-doped metal phosphides.PMID:34318798 | DOI:10.1039/d1cc00535a
