A New Graphdiyne Nanosheet/Pt Nanoparticle-Based Counter Electrode Material with Enhanced Catalytic Activity for Dye-Sensitized Solar Cells

Abstract

A graphdiyne nanosheet/Pt nanoparticle composite shows outstanding catalytic activity for the reaction of I3−/I− redox pairs, i.e., the best among rGO/Pt nanoparticle composites, Pt nanoparticles and Pt foils. This is ascribed to enhanced electron transfer resulting from the easier chemical interaction between Pt and the triple bond of graphdiyne.
