Abstract

The accelerating pace of industrialization has led to escalating water pollution worldwide. Titanium dioxide nanoparticles, as a semiconductor with outstanding photocatalytic properties, hold significant value in photocatalytic degradation of organic pollutants in water. This article focuses on the improvement of the photocatalytic performance of titanium dioxide nanoparticles by doping inorganic metal and inorganic non-metal elements and preparing titanium dioxide nanoparticles from biological precursors. By comprehensively comparing the differences in band gap changes induced by different doping elements, it is found that the correct morphology and purity of the titanium dioxide nanoparticles are even more crucial for the preparation method. Therefore, this paper suggests changing the morphology of titanium dioxide nanoparticles themselves in addition to changing the doping elements, as well as co-doping inorganic metallic elements with inorganic non-metallic elements or improving the spatial three-dimensional structure. In addition, the green synthesis of titanium dioxide nanoparticles or the construction of metal-organic frameworks with organic ligands and composite inorganic semiconductors doped with Co is also a way to improve the photocatalytic efficiency of titanium dioxide nanoparticles, which points to the direction for future researchers.
