Daylight Photoactive TiO2 Sol-Gel Nanoparticles: Sustainable Environmental Contribution

Abstract

Visible-light-photoactive titania micro- or nanoparticles excel in a wide range of industrial areas, particularly in environmental remediation. The sol–gel methodology is one pivotal technique which has been successfully used to synthesize either crystalline and amorphous TiO2 micro- and nanoparticles due to its outstanding chemical simplicity and versatility, along with the green chemistry approach. This short review aims to collect and discuss the most recent developments in visible-light-photoactive titania-based nanoparticles in the environmental remediation area. Titania co-doping, titania composite design, and, recently, amorphous networks have been the most used strategies to address this goal. Finally, a prediction regarding the future of these fields is given.

Transmission Reduction for UV and IR Radiation with Dyed Lyocell Knitted Textiles

“…In addition to the research on radiation-protective materials, a recent field of research is the development of photoactive materials active under illumination with visible light. These materials show strong potential for applications for disinfection and degradation of pollutants [25][26][27][28]. Nowadays, developments in the sustainability of textile production processes are of high importance because textile production is responsible for 5 to 10% of greenhouse gas emissions [29].…”

Synergistic effects of Mg doping on TiO2 for improved toxic gas sensing performance at room temperature

“…Rutile is preferred for high refractive index applications like paints and coatings, while anatase is widely used as a photocatalyst in water purification, solar cells, and self-cleaning surfaces. Brookite has potential in solar cells [12]. TiO 2 also finds applications in heterogeneous lithium-ion batteries, gas sensors, and as an oxidizing agent.…”
