Abstract

Platinum hollow nanospheres are synthesized by Co nanoparticles as sacrificial template and then immobilized on graphene nanosheets (HNPt/G). The as-prepared nanostructure is characterized by TEM (transmission electron microscopy) and EDX (energy dispersion X-ray spectroscopy). The prepared HNPt/G is used as electrocatalyst for HER (hydrogen evolution reaction). For this purpose, GC (glassy carbon) electrode modified by HNPt/G was fabricated (HNPt/G/GC). Electrochemical studies show that HNPt/G has a good electrocatalytic activity toward HER. For comparison solid Pt nanoparticles were synthesized and decorated on graphene (NPt/G). The HNPt/G exhibit an enhanced electrocatalytic performance for HER compared with NPt/G.
