Abstract

Abstract: Nano-powder of ruthenium-titanium composite oxides of different molar ratios (RuxTi1-xO2) are synthesised by TiN impregnation-thermal decomposition method, and then 20 wt% Pd are carried on this powder by microwave polyol method to transform into a kind of anode catalysts (Pd/RuxTi1-xO2) of direct formic acid fuel cells (DFAFC). By X-ray diffraction (XRD) and transmission electron microscopy (TEM), it reveals that the Pd nanoparticles are well-distributed on the surface of composite oxides with claviform and rutile structure. The electrocatalytic oxidation by cyclic voltammetry (CV) and chronoamperometric curves show that the content of Ru in catalysts can influence the electrocatalytic activity and stability of the direct oxidation of formic acid. When the x is 0.3, the electrocatalytic activity and stability are the best.

Key words: ruthenium-titanium composite oxide, direct formic acid fuel cells, palladium catalyst, Electrocatalytic
