Herein, a series of metallo-porphyrins, corroles and phthalocyanines were applied as the key precursors to confirm the influence of macrocyclic cores on the preparation of single- and dual-metal nitrogen-doped carbon (M-N-C) catalysts, and the control the M-N-C catalyst preparation towards accelerating electrocatalyzed hydrogen evolutions could be rationally modulated. Due to the synergetic effect, the dual-metal CoCuTPP@rGO-900 M-N-C catalyst has the best performance on the electrochemically catalyzed hydrogen evolution with onset potentials as −166 mV and Tafel 117 mV·dec. More importantly, these M-N-C catalysts could also be used in a wide range of pH values, such as PBS and KOH medias.

大环前驱体如何影响MNC催化剂？电化学催化析氢的制备及其应用

本文以一系列金属卟啉、咔咯和酞菁为关键前驱体，证实了大环核对单金属和双金属氮掺杂碳（MNC）催化剂制备的影响，并控制了MNC催化剂可以合理地调节加速电催化析氢的准备工作。由于协同效应，双金属CoCuTPP@rGO-900 MNC催化剂在电化学催化析氢方面具有最佳性能，起始电位为-166 mV，Tafel为117 mV·dec。更重要的是，这些 MNC 催化剂还可以在广泛的 pH 值范围内使用，例如 PBS 和 KOH 介质。
