Abstract

The nanocomposite samples, containing copper and iron species in the silica matrix, were prepared by annealing at temperatures up to 1100°C. The samples were investigated by X-ray diffraction analysis, Fourier transform infrared spectroscopy, and cyclic voltammetry. The results of the performed study depict to the presence of a temperature gradient, which acts on the sample during the annealing treatment in the furnace. For the first time, the influence of the temperature gradient on the formation mechanism of the samples was discussed.

热处理对溶胶-凝胶法合成含铜，铁的纳米复合材料形成机理的影响

摘要

通过在高达1100°C的温度下退火来制备纳米复合材料样品，该样品在二氧化硅基质中包含铜和铁。通过X射线衍射分析，傅里叶变换红外光谱和循环伏安法研究了样品。进行的研究结果描述了温度梯度的存在，该温度梯度在炉内退火处理期间作用于样品。首次讨论了温度梯度对样品形成机理的影响。
