| Abstract: A novel titanium-supported nickel electrode(Ni/Ti) was fabricated by a hydrothermal process using NiSO4 and hydrazine as raw materials. The structure of Ni/Ti was characterized by SEM and EDS. Oxidation of hydrazine on the Ni/Ti electrode in 1 mol·L-1 NaOH solution was studied with cyclic voltammograms(CV) and chronoamperometry(CA).The results show that Ni/Ti electrode was electrochemically active towards hydrazine oxidation. The high current density was recorded on the Ni/Ti electrode, and the onset potential for the hydrazine oxidation was -0.3 V as the hydrazine concentration was 70 mmol·L-1. This novel nickel electrode would be a promising anodic material used in direct hydrazine fuel cells. |
