The catalytic properties of non-noble metal catalysts are not comparable to those of noble metal catalysts, such as Pt and Ru, on account of the catalytic thresholds of these non-noble metal catalysts. In order to solve this problem, an efficient P, W-MoS₂/NiSP/NF catalyst was rationally designed through heteroatom (P and W) doping and heterostructure construction. Interestingly, motivated by the synergistic incorporation of W and P, the 2H-phase MoS₂ with limited edge active sites was partially converted into highly active 1T-phase MoS₂ with rich defects, which basically activate the hydrogen evolution reaction (HER)-inert basal plane of MoS₂ and significantly enlarge the number of active sites, ultimately endowing the well-designed P, W-MoS₂/NiSP/NF catalyst with Pt-like HER performance and superior oxygen evolution reaction (OER) performance. Importantly, this work exerts a profound influence on the construction of 1T-MoS₂ with defects, the design of multi-stage structures, and the achievement of Pt-like catalytic performance.

在多级催化剂中合理掺杂P和W以触发类似Pt的电催化性能

由于这些非贵金属催化剂的催化阈值，非贵金属催化剂的催化性能不能与诸如Pt和Ru的贵金属催化剂的催化性能相比。为了解决这个问题，通过杂原子（P和W）掺杂和异质结构的构建合理设计了一种高效的P，W-MoS ₂ / NiSP / NF催化剂。有趣的是，由于W和P的协同结合，具有有限边缘活性位的2H相MoS ₂被部分转化为具有丰富缺陷的高活性1T相MoS ₂，这基本上激活了放氢反应（HER）惰性MoS _2的基面并显着增加了活性位点的数量，最终使精心设计的P，W-MoS ₂ / NiSP / NF催化剂具有类似Pt的HER性能和优异的析氧反应（OER）性能。重要的是，这项工作对具有缺陷的1T-MoS _2的构造，多级结构的设计以及类Pt催化性能的实现产生了深远的影响。
