Cu-doped TiO2 catalysts for catalytic hydrogenation/degradation of organic compounds in water

Abstract

In this study, CuCl₂ was attached to TiO₂ support material using two different methods, yielding two new catalysts. To analyze the catalysts' structural and morphological properties, various techniques were used, including Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. The catalytic activity of the prepared catalysts was tested for the catalytic degradation reactions of 2-nitroaniline, 4-nitroaniline, 4-nitrophenol, and eosin yellow compounds in the presence of NaBH₄ in an aqueous solution. It was discovered that the prepared materials are extremely active catalysts. The degradation reactions were efficient, and the catalysts showed excellent selectivity for the organic compounds. These findings suggest that the structural and morphological properties of the prepared catalysts play an important role in increasing their catalytic activity. The catalysts' high activity can be attributed to their pore size distribution, and surface chemistry.
