Non-noble Metal Based Catalysts with Hydrogen Spillover Mechanism for Carbon-Based Hydrogen Storage Materials

Catalysts with hydrogen spillover mechanisms can significantly enhance the hydrogen storage density of carbon-based porous materials under ambient conditions, attributed to its hydrogen adsorption energy improving by cracking hydrogen molecules into active hydrogen (hydrogen ions or hydrogen radicals), which is considered as a promising strategy for optimizing hydrogen storage performance of porous materials. The developing of non-noble metal based catalysts with hydrogen spillover mechanisms is currently a research hotspot and development direction. Based on this, the catalyst research progresses based on the non-noble metal materials are summarized to clarifies the factors affecting the hydrogen spillover effect of non-noble metal based catalysts. This article looks forward to the research and development direction of non-noble metal based catalysts for carbon-based porous materials, which hope to promote the development of non-noble metal based catalysts and accelerate the industrial application of porous solid hydrogen storage materials.
