Electrochemical synthesis of hydrogen peroxide on BiNiO x −4 and in situ disinfection

The BiNiO x −4 catalyst prepared by sol–gel method has high selectivity for electrocatalytic production of H 2 O 2 (93.2% at 0.4 V RHE ), as well as a yield of 223 mmol L −1 in 2 h, and favourable bactericidal effect. The mechanism involved was demonstrated by DFT calculations.
