“…Therefore, the antireflection multilayer coatings could be used as self-cleaning and protective surfaces. Similarly, Villamayor et al [108] deposited TiO 2 and NiO/TiO 2 coatings using DC and pulsed DC reactive magnetron sputtering on glass slides and monocrystalline silicon wafers as substrates. After deposition, annealing of the coatings at 450 • C for 2 h was performed to obtain anatase TiO 2 .…”

To address environmental pollution and energy shortage issues, titanium dioxide (TiO2)-based photocatalysts, as an efficient pollution removal and fuel production technology, have been widely used in the field of photocatalysis. In practical applications, TiO2-based photocatalysts are usually prepared on various substrates to realize the separation of the catalyst from water and improve photocatalytic stability. Herein, the research progress of TiO2-based heterogeneous photocatalytic coatings deposited on glass substrates with various deposition techniques is reviewed. Such TiO2-based composite coatings obtained using different techniques showed excellent self-cleaning, pollution removal, air purification, and antibiosis performance. The various deposition techniques used for the preparation of TiO2 coatings, such as wet chemical deposition (WCD), electrodeposition, physical vapor deposition (PVD), and chemical vapor deposition (CVD) were discussed together with photocatalytic applications by highlighting the typical literature. Finally, the challenges and prospects of developing TiO2-based heterogeneous coatings were put forward.

The use of semiconductor photocatalysts for the hydrogen evolution reaction shows good promise for effectively alleviating the existing energy shortage. Moreover, ternary metal sulfides also exhibit stronger photoresponse performance and suitable band structures, leading to good photocatalytic activity. However, carrier recombination easily occurs in ternary metal sulfides, negatively affecting their photocatalytic performance. In order to address the above issues, this study achieved limited improvement in the electron recombination problem of ternary sulfides through a dual strategy of constructing a heterogeneous structure to quickly export electrons and extracting electrons through the loading of a co catalyst. The combination of B doped TiO2 and nano flower shaped ZnIn2S4 photocatalyst effectively increases the catalytic active sites, widens the absorption band edges, and improves the efficiency of photo generated electron and hole separation. The loading of NiO as a cocatalyst increased the light absorption intensity, changed the direction of electron transfer enrichment, and provided hydrogen production sites. Compared to pure TiO2, which had a band gap of 2.37 eV, the band gap of the modified catalyst decreased to 2.27 eV. Moreover, the hydrogen evolution rate increased by 2.17 fold from 3.84 mmol/(g ⋅ h) to 8.33 mmol/(g ⋅ h). The separation and migration rates of electrons and holes were significantly enhanced, which promoted rapid charge transfer. Moreover, the modified catalyst achieved Rhodamine B (RhB) and Congo red photocatalytic degradation rates of 99.91 % and 97.98 % in 1 h under simulated sunlight irradiation.
