It was reported for the first time that phosphorictungstenic acid （PWA） could promote the oxygen reduction reaction （ORR） and inhibit the methanol oxidation reaction at the cathodic Pt/C catalyst in the direct methanol fuel cell （DMFC）. When the weight ratio of PWA to Pt/C is 1, the composite catalyst increases the reduction current of oxygen by about 38% and decreases the oxidation current of methanol by about 76% compared with that of the Pt/C catalyst.

An ordered carbon nanotubes (CNTs) film, which was template-synthesized within the porous of an alumina template, modified glassy carbon electrode is fabricated. The electrode exhibits potent electrocatalysis for NADH oxidation in PBS (pH 6.8) with a diminution of the overpotential of more than 600 mV. The anodic peak current increases linearly with NADH concentration from 2?0-5 mol/L to 1?0-3 mol/L with the detection limit of about 5?0-7 mol/L.

The PdCo bimetallic hollow nanospheres with 80 nm average diameter and around 9.0 nm thickness of the shell were prepared with a special reduction method and characterized with transmission electron microscopy （TEM）, X-ray diffraction （XRD） and energy dispersive spectroscopy （EDS）. The electrochemical measurements illustrated that the electrocatalytic activity of the PdCo bimetallic hollow nanospheres for the oxidation of formic acid is much higher than that of the Pd solid nanospheres.

The electrochemistry of di-μ-oxo-dimanganese complex was investigated. It was found that no redox peak was observed in the cyclic voltammogram (CV) of the complex at the bare gold electrode, but at thiouracil-modified gold electrode, a pair of redox peaks were observed showing that thiouracil can promote the proton-coupled electron transfer reaction of the complex.
