摘要
N-doped carbon-modified carbon nanotube/Pt-Ni alloy catalysts were prepared via a thermal decomposition of Ni-MOF with dual organic ligands (triethylene diamine and terephthalic acid). Different from the individual Pt and Ni nanoparticles derived from Ni-MOF with a single organic ligand, the dual organic ligands bestow the obtained Pt-Ni nanoparticles with alloy structure. The fabricated catalyst exhibits significant hydrogen evolution reaction activity and stability in the alkaline solution, with an overpotential of −196 mV to achieve 10 mA cm−2. Moreover, the TOF value of CNT/Pt-Ni catalyst is 2.1 times greater than the incumbent commercial Pt/C catalyst (at the overpotential of −300 mV), demonstrating it as a promising electrocatalyst for water splitting reaction. N-doped carbon-modified CNT/Pt-Ni alloy catalysts were prepared via a thermal decomposition of Ni-MOF with triethylene diamine and terephthalic acid as the organic ligands. Different from the individual Pt and Ni nanoparticles derived from Ni-MOF with single organic ligand, the dual organic ligands bestow the Pt-Ni alloy nanoparticles. The fabricated catalyst exhibits significant HER activity and stability under the alkaline solution.
