A novel heterojunction material, with electron-rich graphdiyne as the host and molybdenum disulfide catalytic center (eGDY/MDS), to produce ultraefficient hydrogen-evolution reaction (HER) at all pH values is described. It a surprise that metallic conductor combined from two semiconductor materials, eGDY MDS, leads optimal free energy (ΔGH ) enhancement in intrinsic HER performances. The calculated experimental results indicate eGDY/MDS shows greatly enhanced activities high stabilities both acidic alkaline conditions; these approach outstanding performances of state-of-the-art noble-metal-based catalysts. better activity than Pt/C media remarkable photocurrent density. originates facilitated electronic transfer kinetics, conductivity, more exposed active sites, excellent mass transport.
