Noble-Metal-Free Ni-N-C Catalyst for Efficient Electrochemical Synthesis of Hydrogen Peroxide from Oxygen Reduction Reaction Under Both Acidic and Alkaline Conditions

H2O2 is a valuable, environmentally friendly oxidizing agent with a wide range of applications from the provision of clean water to the synthesis of valuable chemicals. The on-site electrocatalytic production of H2O2 would bring the chemical to uses beyond its present reach. The successful commercialization of electrochemical synthesis of H2O2 through 2e- oxygen reduction reaction (ORR) and the efficiency of the process depends greatly on the …
