Özet:

High-range and high-quality TiO2 nano-pipe (TiO2-NTs) for methanole fuel cells are prepared as catalyst support. Following the preparation of the sequential TiO2-NTs, small amounts of nikel (Ni) nanothanets (TiO2-NTs-Ni) are electrochemically destroyed on the surface. The surface and crystal structure of the anot catalysts prepared in this way is characterized by the scaned electron microscope (SEM), the conversion voltameter (CV) and the X-ray breakdown (XRD) respectively. Prepared TiO2-NTs-Ni anot catalysts for methanol oxidation catalyst activities in 1 M methanol solution containing 1 M KOH CV and their stability and resilience over time have been studied with the technique of chronoamperometry (CA). According to the results obtained, TiO2-NTs did not show any activity in the methanol environment, while covering the surface with a small amount of Ni increased the oxidation of methanol. As the amount of Ni on the surface of the catalyst increases, the oxygenation rate increases. As the speed of CV scanning increases, an increase in oxidation pic flow has been observed. According to the CA results, the catalysts prepared showed a stable and enduring structure in the working environment for an hour. Prepared TiO2-NTs-Ni can be used as an effective anot catalyst for methanol fuel cells.
