Abstract
AbstractElectrochemical conversion of alkanes to high value‐added oxygenated products under a mild condition is of significance. Herein, we effectively couple the electrocatalysis of H2O2 with the thermo‐catalysis of propane oxidation in the cathode of proton exchange membrane fuel cell. Specifically, H2O2 is in‐situ generated on the nitric acid‐treated carbon black (C‐acid) via 2e− process of oxygen reduction reaction, and then transports to the Fe active sites of MIL‐53 (Al, Fe) metal–organic frameworks for propane oxidation. Based on this strategy, the space‐time yield of C3 oxygenated products of propane oxidation reaches 2.65 μmol h−1 cm−2, which represents a new benchmark for electrochemical alkane oxidation in the fuel‐cell‐type electrolyzer. This study highlights the importance of multifunctional composite catalysts in the field of electrosynthesis.
