Abstract

Single-atom catalysts (SACs) and atomically dispersed catalysts have attracted growing attention because the number of active sites, with unpredictable catalytic activity can be maximized. We have designed highly stable and high-loading atomically dispersed catalysts in porous architectures. We synthesized Ru SAC supported on WC1-x (Ru SA/WC1-x) for alkaline HOR reaction by an in situ high-temperature annealing strategy to induce strong interactions between Ru SA and the WC1-x support without forming of impurities (e.g., WOx) on the surface during the carburization, resulting in high Ru SA loading of up to 6.1 wt.. We also report self-assembly-assisted dynamic placement of noble metals selectively on multifunctional carbide supports for alkaline hydrogen electrocatalysts. The strategy for stabilizing the interface of next-generation high-capacity rechargeable batteries, including lithium-metal and sodium-metal batteries will be also discussed.
