TL;DR: This review summarizes recent advances of doped TiO2-based photocatalysts used in hydrogen production and the degradation of organic pollutants in water to solve global problems of energy conservation and ecology.
Abstract: The growth of industrialization, which is forced to use non-renewable energy sources, leads to an increase in environmental pollution. Therefore, it is necessary not only to reduce the use of fossil fuels to meet energy needs but also to replace it with cleaner fuels. Production of hydrogen by splitting water is considered one of the most promising ways to use solar energy. TiO2 is an amphoteric oxide that occurs naturally in several modifications. This review summarizes recent advances of doped TiO2-based photocatalysts used in hydrogen production and the degradation of organic pollutants in water. An intense scientific and practical interest in these processes is aroused by the fact that they aim to solve global problems of energy conservation and ecology.

TL;DR: In this article, a terephthalic acid functionalized g−C3N4 (TACN) was newly developed and utilized in the development of visible-light-driven magnetically recyclable TACN/TiO2/Fe3O4@SiO2 (TTFS) Z-scheme heterojunction nanophotocatalyst.
Abstract: A terephthalic acid functionalized g−C3N4 (TACN) was newly developed and utilized in the development of visible–light–driven magnetically recyclable TACN/TiO2/Fe3O4@SiO2 (TTFS) Z–scheme heterojunction nanophotocatalyst. The characterization was performed by BET surface area analyzer, TEM, UV–vis DRS, VSM, XRD, and XPS. To ensure its practical applicability, the experiments were also performed for real sewage effluent spiked with pharmaceuticals and personal care products (PPCPs) in which degradation of 97 % of the 2 mg L−1 of ibuprofen in 120 min, 94 % of the 2 mg L−1 of benzophenone–3 in 150 min, and 94 % of the 2 mg L−1 of carbamazepine in 240 min was achieved upon 330 W m−2 of integrated visible light irradiance. The recycling of the TTFS nanophotocatalyst was achieved without adopting calcination or heating within a short contact time (5 h), maintaining a photocatalytic efficiency of over 83% after 5 cycles, which proves its potential for real practical applications.

TL;DR: In this paper, the authors highlight the investigation and development of TiO2 photocatalyst film by sol-gel method with special emphasis on the photodecolorization of synthetic dyes and antibacterial activities.
Abstract: Photocatalysis has recently emerged as an advanced, green, and eco-friendly process for the treatment of wastewater and air, and antimicrobial disinfection applications. In this context, TiO2 nanostructures have been shown to be the prominent photocatalyst candidates due to their low cost, non-toxicity, and ease of fabrication. This review highlights the investigation and development of TiO2 photocatalyst film by sol-gel method with special emphasis on the photodecolorization of synthetic dyes and antibacterial activities. Furthermore, various synthesis methods for the preparation of TiO2 films and their advantages, as well as limitations, are summarized. Finally, recent advances in TiO2 films by sol-gel method for dye degradation and antibacterial activities, challenges, and future perspective are discussed.
