摘　　要：富勒烯(C_(60))与Fe基、Ni基四苯基卟啉(TPP)通过π电子体系的共轭效应实现了自组装,通过梯度退火工艺,制备了氮掺杂石墨碳负载FeNi合金纳米颗粒复合电催化剂(C_(60)/FeNiTPP-1)。采用XRD、SEM、TEM、XPS对C_(60)/FeNiTPP-1进行了表征,通过电化学测试对其析氢反应(HER)及氧还原反应(ORR)性能进行了评价。结果表明,C_(60)/FeNiTPP-1为HER和ORR双功能电催化剂,HER过程中,在浓度1.0 mol/L的KOH溶液中仅需164 mV的析氢过电势即可达到10 mA/cm^(2)的电流密度,并且催化稳定性能保持至少20 h;ORR过程中,C_(60)/FeNiTPP-1的半波电位为0.824 V(vs.可逆氢电极电势),且具有良好的稳定性和甲醇耐受性。Nitrogen-doped graphite-carbon supported FeNi alloy nanoparticle composite electrocatalyst(C_(60)/FeNiTPP-1)was prepared fromπ-electron conjugation mediated self-assembly of fullerene(C_(60))and Fe-and Ni-based tetraphenyl porphyrin(TPP)via gradient annealing process,characterized by XRD,SEM,TEM and XPS,and evaluated for its hydrogen evolution reaction(HER)and oxygen reduction reaction(ORR)performance by electrochemical tests.The results showed that C_(60)/FeNiTPP-1 was a HER and ORR bifunctional electrocatalyst.In HER process,in 1.0 mol/L KOH solution,only 164 mV of hydrogen evolution overpotential was needed to reach a current density of 10 mA/cm^(2),and the catalytic stability could be maintained for at least 20 h.In ORR process,C_(60)/FeNiTPP-1 exhibited a half-wave potential of 0.824 V(vs.reversible hydrogen electrode),and good stability as well as methanol tolerance.
