With mesoporous structure introduced by ZnCl2 salt and cathodic activation, it demonstrates an onset overpotential as low as 76 mV, a Tafel slope of 58.4 mV dec(-1) and a large normalized exchange current density of 1.72 x 10(-2) mA cm(-2), which are comparable to those of hitherto best metal-free and well-fabricated metallic HER catalystspdfPhysical chemistryMaterials scienceJournal Article1364-5501https://doi.org/10.1039/c5ta00966a351845400002Q1NOIR00337
