Interface confined reactions, which can modulate the bonding of reactants with catalytic centres and influence rate mass transport from bulk solution, have emerged as a viable strategy for achieving highly stable selective catalysis. Here we demonstrate that 1T'-enriched lithiated molybdenum disulfide is powerful reducing agent, be exploited in-situ reduction metal ions within inner planes to form zero valent metal-intercalated disulfide. The confinement platinum nanoparticles layered structure leads enhanced hydrogen evolution reaction activity stability compared catalysts dispersed on carbon support. In particular, surface accessible charged species like proton ions, while blocking poisoning by larger sized pollutants or neutral molecules. This points way forward using intercalated compounds energy related applications.
