摘要:硫氮共掺杂的有序介孔碳(SN-OMC)是通过一步复制路线合成的,双硫腙在SN-OMCs的制备过程中作为单一的碳、硫、氮前驱物。对此非金属催化剂进行物理化学表征,并在碱性电解质中对其催化氧还原反应(ORR)的电化学性进行了评估。在900℃下得到的SN-MOC展现了用于ORR反应的高电催化活性,以及可观的耐久性和耐甲醇性;介孔碳孔道中硫和氮的协同效应有利于提高SN-MOC的氧还原催化活性。
The ordered mesoporous carbons co-doped with sulfur and nitrogen (SN-OMC)are synthesized via one-step nanocasting route.Diphenylthiocarbazone is used as a single precursor for carbon,sulfur and nitrogen in the preparation of SN-OMCs.These metal-free catalysts are subj ected to physicochemical characterization and electrochemical evaluation toward the oxygen reduction reaction (ORR)in an alkaline electrolyte.SN-OMC obtained at 900 ℃ exhibits a high electrocatalytic activity for ORR and the impressive durability and methanol-torrence.The synergistic effect of nitrogen and sulfur in mesoporous carbon walls may contribute to high oxygen reduction performance of SN-OMC.
