Abstract

A high electrocatalytic performance Pt/ZnO/KB is well fabricated by a solution plasma technique in water at atmospheric pressure. Their electrocatalytic performance toward methanol oxidation is evaluated in alkaline with light irradiation or in dark. The electrocatalytic activity of Pt is improved in dark because the distribution and reactive sites of Pt nanoparticles are improved by coupling ZnO. And higher electrocatalytic activity is detected under light irradiation because of synergistic effect of photo- (ZnO) and electro-catalyst (Pt). Compared with several morphologies ZnO, ZnO nanowires give better catalytic activity for methanol oxidation than porous ZnO nanosheets because ZnO nanowires possess better electron transport property and smaller resistance. Under light irradiation, Pt/ZnO/KB coupled with ZnO nanowires shows over 3 times higher catalytic activity (ca. 964 mA mg_Pt⁻¹) than Pt/KB (ca. 306 mA mg_Pt⁻¹). And the tolerance to CO-poisoning and stability of Pt/ZnO/KB are also improved. Therefore, Pt/ZnO/KB nanocomposite will be a highly efficient potential anode catalyst in DMFCs with light irradiation.
