水电解对于可持续制氢至关重要。本工作通过在N2气氛下对Pd掺杂的金属有机骨架（MOFs）进行直接退火，制备了高效稳定的PdCo合金催化剂（PdCo@CN）。在0.5 M H2SO 4溶液中，PdCo@CN表现出良好的电催化性能，其过电位为80 mV，Tafel斜率为31 mV dec（-1），循环稳定性为10000次。研究表明，贵金属掺杂的MOFs是制备低贵金属含量的高活性合金电催化剂的理想前驱体。
The water electrolysis is of critical importance for sustainable hydrogen production. In this work, a highly efficient and stable PdCo alloy catalyst (PdCo@CN) was synthesized by direct annealing of Pd-doped metal organic frameworks (MOFs) under N-2 atmosphere. In 0.5 M H2SO4 solution, PdCo@CN displays remarkable electrocatalytic performance with overpotential of 80 mV, a Tafel slope of 31 mV dec(-1), and excellent stability of 10 000 cycles. Our studies reveal that noble metal doped MOFs are ideal precursors for preparing highly active alloy electrocatalysts with low content of noble metal.
