Noncovalent phosphorylation of CoCr layered double hydroxide nanosheets with improved electrocatalytic activity for the oxygen evolution reaction

Noncovalent phosphorylation of CoCr layered double hydroxides (LDHs) was successfully performed for the first time by blending CoCr LDHs with a precursor solution of P2O5 dissolved in isopropanol. The as-prepared material exhibits a higher oxygen evolution reaction electrocatalytic activity than those based on pristine CoCr LDHs and commercial RuO2.
