![]() RHE) than for the catalysts reported before. Higher productivity of H 2O 2 was obtained (2476 mmol g catalyst h −1 at 0.3 V vs. The catalyst exhibited higher selectivity (∼90%) and current efficiency (∼95%) than pristine CMK3 (∼50% and ∼55%) in alkaline solution. Only 1 minute was consumed for the conversion of pristine CMK3 to a high-performance electrocatalyst via a microwave treatment and liquid nitrogen freezing process. ![]() Here, we prepared a high-performance electrocatalyst from commercial mesoporous carbon, CMK3, via microwave treatment for H 2O 2 production. In practical applications, developing high-performance nonprecious metal or metal-free electrocatalysts with cheap and commercially available source materials is challenging. Electrochemical production of hydrogen peroxide (H 2O 2) via oxygen reduction is a two-electron electrochemical process that has promising applications in production.
