摘要

我们提出了一种创新的制备方法，即采用两步热解工艺合成具有优异氢气进化性能的 Zn-Co 双金属催化剂。在合成的 Zn1Co1-SNC 催化剂中，Zn 和 Co 之间存在很强的相互作用，同时与 S/N 原子之间存在协同效应，共同促进了催化剂结构的稳定性。实验结果表明，该催化剂在 10 mA/cm2 电流密度下的过电位仅为 49 mV，即使循环 5000 次后仍能保持良好的氢气进化性能。

An asymmetrically coordinated Zn–Co diatomic site catalyst for efficient hydrogen evolution reactions†

We propose an innovative preparation method, namely, a two-step pyrolysis process, to synthesize Zn–Co bimetallic catalysts with excellent hydrogen evolution performance. In the synthesized Zn₁Co₁–SNC catalyst, there exists a strong interaction between Zn and Co, along with synergistic effects with S/N atoms, collectively promoting the stability of the catalyst structure. Experimental results demonstrate that the overpotential of this catalyst at 10 mA cm⁻² current density is only 49 mV, and it maintains excellent hydrogen evolution performance even after 5000 cycles.
