摘要: Abstract In this paper, Pt nanoclusters are firstly decorated on the surface of two dimensional (2D) g-C3N4 nanosheets. Furthermore, 1D CdS nanowires introduced to form heterojunction g-C3N4/CdS. The as-prepared Pt/g-C3N4/CdS shows 7.4 times improved electrocatalytic performance methanol oxidation under visible light (>420 nm) irradiation compare dark condition. Moreover, stability corresponding electrode is significantly by evaluating chronoamperometric and chronopotentiometry curves. synergistic effects photo- electro-catalysis together with efficient charger separation in g-C3N4/CdS contribute above improvements. present studies provide an effective pathway design a as photo-activated support application direct fuel cell.
