摘要：
The ultrafine Pt nanoparticles (NPs) were decorated on carbon nanotubes (CNTs) via a simple hydrothermal process and the obtained Pt/CNTs composite shows excellent electrochemical HER activity in 0.5 M H2SO4 solution. Benefiting from the synergistic effects between high catalytic activity ultrafine Pt NPs and good conductivity of CNTs, Pt/CNTs catalyst has small overpotential of 24 mV at 10 mA cm-2 and low Tafel slope of 29 mV dec-1.
