Gold nanoparticles (AuNPs) is viewed as a viable electrocatalyst candidate for alcohol oxidation due to the comparable catalytic activity and high poisoning-resistance. Facial synthesis and highly loading capacity of efficient AuNPs catalyst is highly anticipated for alcohol fuel cells. Herein, tiny AuNPs without any surfactant are synthesized successfully via air/water interfacial reaction and anchored in-suit on the surfaces of supported carbon nanotubes in high density. The resultant freestanding composite thin films could be used directly as electrode materials and modify stably electrode with improved stability and operation feasibility. Moreover, the achieved composite film on the modified electrode exhibit efficient electrocatalytic ability for alcohol oxidation, mainly due to abundant active sites and facile electron transfer. This work may expand the scope of cost-effective electrocatalyst for alcohol fuel cells.
