H2 has been considered as a promising successor for traditional fossil fuels due to its sustainable and clean. In H2 production, electrocatalytic hydrogen evolution reaction (HER) is the core step. Many noble metal free electrocatalysts for electrochemical H2 generation have been explored in the past few years. Mo based materials, such as MoxC (x = 1 or 2), MoP, MoS2 and MoxN (x = 1 or 2) have been confirmed as effective electrocatalysts in both acidic and basic conditions with small overpotential, excellent stability and nearly 100% Faradic efficiency in H2 generation. Because of excellent solubility, controllable dimension and various components, Mo based polyoxometallates (POMs), such as [PMo12O40]3−, [Mo7O24]6−, [P2Mo5O23]6−, [Mo6O19]2− and [XMo6O24]4− (X = Co2+, Cu2+, Ni2+), are ideal precursors to synthesize Mo based electrocatalyst. Here, we summarized Mo based hybrid electrocatalysts in form of MoxC, MoP, MoS2 and MoxN with carbon as matrix, which derived from POM since 2013. In this review, we focus on the synthetic strategy and HER activity of these electrocatalyst. We anticipate this review can provide more insight into the structural and composition regulation of POM precursor to design and synthesis Mo based HER electrocatalyst with more excellent activity.

碳为基质的多金属氧酸盐衍生的钼基混合HER电催化剂及其在Zn-H +电池中的应用

H 2具有可持续性和清洁性,因此被认为是传统化石燃料的有希望的后继者。在H 2生产中,电催化制氢反应(HER)是核心步骤。在过去的几年中,已经探索了许多用于电化学生成H 2的无金属贵金属电催化剂。钼基材料,例如Mo x C(x = 1或2),MoP,MoS 2和Mo x N(x = 1或2)已被证实在酸性和碱性条件下都是有效的电催化剂,且过电位小,稳定性极佳H 2中的法拉第效率近100%代。由于[PMo 12 O 40 ] 3−,[Mo 7 O 24 ] 6−,[P 2 Mo 5 O 23 ] 6−,[[ Mo 6 O 19 ] 2−和[XMo 6 O 24 ] 4−(X = Co 2 +,Cu 2 +,Ni 2+)是合成Mo基电催化剂的理想前体。在这里,我们总结了以碳为基质的Mo x C,MoP,MoS 2和Mo x N形式的Mo基杂化电催化剂,这些杂化电催化剂自2013年以来均由POM衍生而成。在本综述中,我们重点研究这些的合成策略和HER活性。电催化剂。我们希望该综述可以为设计和合成具有更优异活性的Mo基HER电催化剂提供更多有关POM前体的结构和组成调节的见解。
