In conventionally used carbon-supported heterogeneous platinum catalysts for hydrogen evolution reaction (HER), low Pt utilization efficiency and poor stability, resulting from weak interactions with the carbon supports, are crucial issues. Here, we report a novel hierarchical structure of TiOx nanoparticles embedded in porous situ growth highly dispersed on surface (Pt-TiOx@C). The as-prepared Pt-TiOx@C electrocatalyst showed excellent catalytic activity during HER an overpotential only 10 mV when current density reached mA cm−2 mass was 9.24 A mgPt−1 at 30 0.5 M H2SO4 solution, thus outperforming commercial Pt/C catalysts. Furthermore, it also exhibited stable over 10,000 CV cycles accelerated degradation test (ADT). This high durability could be ascribed to feature strong metal–support interaction (SMSI) between TiOx. study provides simple effective method designing active electrocatalysts.
