摘要

世界范围内最重要的可再生能源之一是太阳能的利用,太阳能正在迅速发展,太阳能发电厂正在成为许多国家能源基础设施的一部分。对此,具有光伏特性的二氧化钛被广泛应用于将太阳能转化为电能。目的是开发一种在水溶液中稳定的纳米二氧化钛附着在金属钛板表面的方法。对象。通过去除阳极-阴极循环的动电位极化曲线,在恒电位条件下进行电解,研究了钛表面二氧化钛的形成机理。确定了阳极极化过程中,在氢氧化钠(碱性介质)和硫酸钾(中性介质)溶液中钛电极表面形成其氧化物。结果。在浓度为100 g/l的硫酸钾溶液中,钛电极的阳极-阴极极化曲线表明,阳极电流出现在电位+0.2 V的区域。结论。研究表明,钛在氢氧化钠和硫酸钾溶液中阳极极化时,表面会形成氧化膜。结果表明,在透化条件下,二氧化钛薄膜的形成速率极低。

DEVELOPMENT OF A METHOD FOR OBTAINING A THIN TIO2 FILM WITH THE PHOTOELECTRIC PROPERTIES BY THE ELECTROCHEMICAL METHOD
One of the most important sources of renewable energy worldwide is the use of solar energy, which is developing rapidly, and solar power plants are becoming part of the energy infrastructure of many countries. In this regard, titanium dioxide, which has photovoltaic properties, and is used in the conversion of solar energy into electrical energy, is widely used. Purpose is to develop a method for attaching nanostructured titanium dioxide, stable in aqueous solutions, to the surface of a metal titanium plate. Objects. The mechanism of titanium dioxide formation on the titanium surface has been studied by removing the potentiodynamic polarization curves of the anode-cathode cycle, and conducting electrolysis under the potentiostatic conditions. It is established that during anodic polarization, its oxides are formed on the surface of the titanium electrode in the solutions of sodium hydroxide (alkaline medium) and potassium sulfate (neutral medium). Results. The curves of the anode-cathode polarization of a titanium electrode in a solution of potassium sulfate with the concentration of 100 g/l have shown that an anode current appears in the region of the potentials +0.2 V. Conclusion. It has been shown that during anodic polarization of titanium in the solutions of sodium hydroxide and potassium sulfate, an oxide film forms on its surface. It is determined that the formation of a titanium dioxide film occurs at a very low rate under the conditions of transpassivation.
