Amorphous CoFePOx hollow nanocubes decorated with g-C3N4 quantum dots to achieve efficient electrocatalytic performance in the oxygen evolution reaction

g-C 3 N 4 quantum dots decorated on amorphous CoFePOx hollow nanocubes can effectively adjust the electronic structure of CoFePOx substrates and substantially improve the electrocatalytic activity of amorphous CoFePOx nanocubes for oxygen evolution reaction (OER).
