RuO2 nanoparticle-decorated TiO2 nanobelt array as a highly efficient electrocatalyst for the hydrogen evolution reaction at all pH values

RuO 2 nanoparticles decorated TiO 2 nanobelt on titanium plate is active for electrocatalytic hydrogen evolution, requiring overpotentials of 130, 143, and 380 mV to drive 100 mA cm −2 in 0.5 M H 2 SO 4 , 1.0 M KOH, and 1.0 M PBS solution, respectively.
