A Review of the Preparation of Environmentally Friendly Titanium-Based Nano-Oxidation Materials

Abstract

In recent years, water environmental pollution and a series of environmental health issues caused by it have posed severe challenges to the green ecological and healthy development under the guidance of the “Carbon peaking and carbon neutrality” goals. Among them, water pollution dominated by typical pollutants has been continuously concerned due to its high detectability, environmental persistence, and complex governance. However, traditional water treatment technologies still have significant limitations in effectively removing such complex organic pollutants. Therefore, the development of efficient and reliable novel catalytic oxidation systems is urgently needed. Environmental functional materials, due to their diverse structures and almost limitless possibilities for functional design, can effectively contribute to the construction of the above-mentioned novel catalytic oxidation systems. In particular, advanced oxidation systems based on environmentally friendly titanium-based nanomaterials have shown excellent application prospects in adsorption and accelerated catalytic breakdown of organic pollutants and have good environmental friendliness. Therefore, this paper reviews the advantages of titanium-based nanomaterials and systematically outlines the preparation methods of practical TiO2-based nano-oxidation materials and novel MXene-Ti-based nano-oxidation materials.
