同时制备了氮硫双掺杂碳纳米管-介孔碳（D-CNTs-MPC）复合材料，并在碱性介质中作为氧还原反应（ORR）的电催化剂。以纳米caco3为模板，以双核酞菁六磺酸钴为碳、氮、硫前驱体和碳纳米管生长催化剂，采用浇铸法制备了D-CNTs-MPC。D-CNTs-MPC具有短碳纳米管，可粘附在具有中孔的松散堆积的碳上。此外，在不添加其他杂原子前驱体的情况下，将氮和硫掺杂到碳骨架中。电化学行为表明，D-CNTs-MPC是一种活性的、耐甲醇的、稳定的ORR电催化剂。
Nitrogen and sulfur dual doped-carbon nanotubes-mesoporous carbon (D-CNTs-MPC) composite is prepared simultaneously and is used in alkaline media as an electrocatalyst for oxygen reduction reaction (ORR). D-CNTs-MPC is synthesized by casting method using nano-CaCO3as a template, and binuclear cobalt phthalocyanine hexasulfonate as a carbon, nitrogen and sulfur precursor as well as the catalyst for growth of CNTs. D-CNTs-MPC possesses short CNTs adhering to loosely packed carbon with mesopores. Moreover, nitrogen and sulfur are doped into the carbon framework without addition of other heteroatom-containing precursor. The electrochemical behavior shows that D-CNTs-MPC is an active, methanol-tolerant and stable electrocatalyst for ORR.
