Molybdenum Diselenide–Manganese Porphyrin Bifunctional Electrocatalyst for the Hydrogen Evolution Reaction and Selective Hydrogen Peroxide Production
نویسندگان
چکیده
Electrochemical reactions for hydrogen and peroxide production are essential energy conversion to diminish crisis, but still lack efficient electrocatalysts. Development of non\-noble metal bifunctional electrocatalysts evolution 2e oxygen reduction reaction ease kinetics is a challenging task. Integration single components by employing easy strategies provides key\-step towards the realization highly active In this vein, MoSe2 owns catalytic sites high specific surface area suffers from insufficient conductivity performance that noble\-metals provide. Herein, was used as platform incorporation manganese metallated porphyrin. The developed hybrid, namely MoSe2\-MnP, initial metal\-ligand coordination subsequent grafting with MnP fully characterized electrochemically assessed. electrocatalyst lowered overpotential toward evolution, improved charge transfer processes extremely stable after 10000 ongoing cycles. Simultaneously, rotating ring disk electrode analysis showed proceeds through pathway selective yield 97 percent. new facile modification route can be applied in diverse transition dichalcogenides will help development advanced functional materials.
