Latest progress based on doped-TiO2 photocatalysis materials: Fabrication and applications

TiO2, with its low toxicity, high chemical stability, low energy consumption, and environmental compatibility (such as low energy consumption, low operating temperature, fine water insolubility, ease of availability and biological inertness), insured the TiO2 to be a prominent candidate serving as a potential photocatalyst to address the organic pollutants. And also, most of photocatalytic materials based on TiO2 have already been verified to acquire tremendous successes in the field of environmental decontamination. Although great efforts have been devoted to the TiO2-based photocatalysis materials, the relationship between fabrication and practical feasibility in photoremediation remains underexplored due to various limitations. Keep this in mind, this review mainly put an emphasis on summarizing, sorting and discussing the dependency relationship between the application performance and fabrication strategies, thus offering a valuable guidance and evaluation of TiO2-based photocatalysts in actual environmental decontamination caused by anthropogenic contaminants. In view of this, some specific application examples would be systematically enumerated and summarized, including dyes removal, pharmaceuticals degradation, phenol and other pollutants disposal. In conclusion, This review has attempted to inspire researchers to explore the benefits of photocatalysts based on TiO2 and advance their development and practical applications.
