	Abstract:Preparation of nanorod structures using a simple hydrothermal method α-MnO2, and then apply a certain negative voltage to 1 M LiOH, 1 M NaOH and 1 M KOH alkaline electrolytes to prepare electrochemically activated α-MnO2。 The results show that under the activation of negative voltage, alkali metal ions in the electrolyte will be embedded α- In the lattice of MnO2, thereby improving the electrical conductivity of the material. In addition, the embedded alkali metal ions can increase α- The lattice spacing of MnO2 is conducive to full contact between the active substance and the electrolyte. In electrochemical testing, the optimal activation voltage for the three electrolyte solutions of 1 M LiOH, 1 M NaOH and 1 M KOH is -1.2 V. At this activation voltage, the specific capacitance after activation in the three solutions was 155.0 F g-1, 148.4 F g-1, and 140.8 F g-1, respectively, which increased by 210%, 197%, and 182% compared to the pure sample, respectively. At the same time, the cycle performance was improved from 74.6% of the pure sample to 96.9%, 89.4%, and 91.9% of the activated sample. After activation, the magnification performance of the sample is also improved compared to the pure sample. This indicates that electrochemical activation is feasible for the modification of manganese dioxide.????

	2. Effect of anode composition on the electrochemical properties of the direct hydrazine fuel cell

	Abstract:A composite catalyst has been prepared by mixing Ni powder, surface-treated Zr-Ni alloy and Pd/C and used as the anode catalyst in the direct hydrazine fuel cell (DHFC). The catalytic activity of these catalysts is evaluated by linear potential sweep, electrochemical impedance spectra (EIS) analysis, polarization measurement. A maximum power density of 106 mW cm-2 has been achieved by using the composite catalyst as the anode catalyst and Pt/C as the cathode catalyst at 0.407 V under ambient conditions. It is found that the composite catalyst shows lower polarization than other catalysts. Results from linear potential sweep and EIS confirm that the cell performance is determined by the anode electrocatalysis towards the oxidation of hydrazine.
