A　kind　of　electro-catalyst　with　high　efficiency　is　proposed　for　hydrogen　evolution　reaction　in　this　paper　and　such　an　electro-catalyst　exposes　its　outstanding　electro-catalytic　performance　and　high　stability　in　the　hydrogen　evolution　reaction　in　0.5　M　H2SO4　electrolyte.　In　detail,　at　the　current　density　of　10　mA　cm(-2),　the　overpotential　of　Pt/CNT-H　(19　mV)　was　significantly　lower　than　that　of　commercial　Pt/C　catalyst　(38　mV).　The　excellent　catalytic　performance　of　such　kind　of　electro-catalyst　shall　be　contributed　to　synergistic　effect　caused　by　Platinum　nano-particles　and　carbon　nanotubes　and　the　cross-linked　three-dimensional　structures.
