Palladium–nickel catalysts based on ordered titanium dioxide nanorod arrays with high catalytic peformance for formic acid electro-oxidation

Here, a novel DFAFC anode catalyst is presented. Due to the 3D catalytic structure and alloying effect, the mass activity and long-term stability of the Pd2Ni3–TiO2 towards FAO are higher than that of Pd–TiO2 and commercial PdC.

Abstract Mass activity and long-term stability are two major issues in current fuel cell catalyst designs. While supported catalysts normally suffer from poor long-term stability but show high mass activity, unsupported catalysts tend to perform better in the first point while showing deficits in the latter one. In this study, a facile synthesis route towards self-supported metallic electrocatalyst nanoarchitectures with both aspects in mind is outlined. This procedure consists of a palladium seeding step of ion track-etched polymer templates followed by a nickel electrodeposition and template dissolution. With this strategy, free-standing nickel nanowire networks which contain palladium nanoparticles only in their outer surface are obtained. These networks are tested in anodic half-cell measurements for demonstrating their capability of oxidising methanol in alkaline electrolytes. The results from the electrochemical experiments show that this new catalyst is more tolerant towards high methanol concentrations (up to $${5}\,\hbox{mol}\,\hbox{L}^{-1}$$ 5 mol L - 1 ) than a commercial carbon supported palladium nanoparticle catalyst and provides a much better long-term stability during potential cycling.

Oxidation Of Glucose

A novel nickel nanocomposite electrode supported by 3D ordered silicon microchannel plates (MCP) had been reported and its electrocatalytic toward the oxidation of glucose for sensor had been studied. The 3D ordered Si MCP electrodes were first fabricated by electrochemical etching and then Nickel nanoparticles were deposited onto the sidewall of the MCP via electroless deposition followed by annealing at 300°C for 300 s under argon to stabilize the structure. The morphology of the Ni/Si-MCP electrode was characterized by Scanning electron microscope (SEM) and X-ray diffraction (XRD). The electrochemical methods were employed to investigate the Ni/Si-MCP materials. The Ni/Si-MCP nanocomposites exhibit superior electrocatalytic properties towards glucose electro-oxidation in alkaline solutions, in addition to showing excellent long-term stability and good reproducibility.
