“…Most of its structure was still in amorphous phase, meaning that it tends to form agglomeration and pores on its surface. Furthermore, because small-sized TiO2 nanoparticles readily agglomerate during synthesis process and application, their photocatalytic activity is significantly diminished [27]. The morphology of TiO2 was discovered to be significantly influenced by the temperatures at which heating occurred [28].…”

The research in material science has actively pursued the creation of self-cleaning materials, especially for windows. Titanium dioxide (TiO2) is considered a promising substance for developing hydrophilic self-cleaning surfaces due to its photocatalytic activity. In this research, TiO2 nanoparticles were synthesized using TiCl3 as the precursor and co-precipitation as the experimental method in order to obtain anatase phase. The nanoparticles, then, was deposited by spray pyrolysis technique with different spraying time; 1, 2, 3, and 4 minutes and different types of TiO2 nanoparticles—synthesis and commercial—as the primary variations. TiO2 thin film was formed using ethyl cellulose as binder and isopropyl alcohol as solvent. The synthesized TiO2 nanoparticles and deposited thin film were, then, characterized using XRD, Maud software, UV-Visible Spectrophotometer, optical microscope, and SEM. The higher band gap energy value of TiO2 thin films was obtained with the average of 3.746 eV and 3.744 eV for TI(S) and TI(C), respectively, as a result of ethyl cellulose composition on the thin film. The thin film was categorized as hydrophilic.

“…The addition of electron acceptors significantly increases the efficiency of the photocatalytic process [212,213]. Electron acceptors prevent the recombination of e − -h + by separation of free charge carriers and an influence of e − [214][215][216].…”

Titanium dioxide (TiO2), one of the most frequently used materials in general, has emerged as an excellent photocatalytic material for environmental applications. In this review, principles and mechanisms of the photocatalytic activity of TiO2 have been analyzed. Structural and physical specificities of TiO2 nanoparticles, such as morphology, crystal structure, and electronic and optical properties, have been considered in the context of photocatalytic applications. A review of the influence of several factors, such as the type and dimensions of photocatalyst particles, pH of the solution, the influence of oxidants/electron acceptors, and light intensity on photocatalytic properties of TiO2, has been provided. Superhydrophilicity as an intrinsic property of the TiO2 surface was discussed through surface reconstruction on TiO2 during the reversible hydrophilic changes. Additionally, attention was paid to improving the photocatalytic properties of TiO2 particles through aggregation and agglomeration.
