Carbon fiber cloth supported Au nano-textile fabrics as an efficient catalyst for hydrogen peroxide electroreduction in acid medium

摘要: Abstract The size-controlled hierarchical textile-like Au nanostructures supported carbon fiber cloth (Au NTs/CFC) is successfully fabricated through a simple low-cost electrochemical route. electrodes are characterised by scanning electron microscopy equipped with an energy dispersive X-ray spectrometer, transmission and diffractometer. Without any conducting carbons polymer binders, the 3D electrode unique structure directly used as electrocatalyst for H2O2 reduction in acid solution catalytic performance evaluated voltammetry chronoamperometry. NTs/CFC exhibits much higher activity remarkably improved utilization of than nanoparticles NPs/CFC) prepared same method owing to its structure. In 3.0 mol L−1 H2SO4 + 0.1 mol L−1 H2O2, potential 0 V, current of −0.72 A cm−2 mg−1 can be obtained on only of −0.09 A cm−2 mg−1 achieved NPs/CFC electrode. All these results reveal that novel excellent superior stability electroreduction medium, benefitting from which ensure high catalyst.
