The methanol and ethylene glycol electrooxidation on palladium electrode in acidic solution has been investigated by cyclic voltammetry and in situ Fourier transform infrared spectroelectrochemistry. It shows that the oxidation of methanol and ethylene glycol at Pd electrode cannot proceed until over 1. 5 V in acidic and neutral media. The overpotential decreases and the peak current density increases with the reduction in pH values. The formation of the oxygen-containing species significantly affects the alcohol oxidation on Pd electrode. The in situ FTIR spectroscopic measurements show that the oxidation products of ethylene glycol on Pd electrode are CO2 and oxalic …

Using KH-550 as precursors,gel thin films were formed on fabric by sol-gel method.By complexed with palladium ions due to the presences of amido and hydroxide in the gel thin films,the aggregation of palladium particles was inhibited.Therefore,Palladium could exhibit better catalytic activity in the process of electroless plating.The surface morphology of fabric was observed by SPM and SEM.Campared with the traditional pretreatment process,no SnCl2 was needed.This method reduced pollution,shortened process flow and reduced the amount of noble metals.
