摘要
阐述了氢溢流机理的基本概念,总结了氢在负载金属上的吸附位置和解离方式、氢在金属颗粒与炭材料间的扩散方式、氢在炭表面上的吸附位和解吸机理。指出了负载金属炭材料在储氢应用中的多元合金和表面官能团等研究方向。
A fundamental overview of spillover mechanism on hydrogen storage on carbon materials adsorbents is given, including the adsorption sites and dissociation ways of hydrogen molecule on the metal nanoparticles doped, the diffusion of the spillover hydrogen atoms between a spillover source and a secondary receptor at ambient temperature, the adsorption positions and desorption mechanisms of hydrogen atoms adsorbed on the carbon materials surface. In order to increase hydrogen storage capacities of carbon materials doped with metal nanoparticles, the effect of multicomponent alloy and surface functional groups will be beneficial to discuss for the future studies.
