“…A photocatalyst is a chemical reaction induced by light, specifically using UV radiation with wavelengths ranging from 100 to 400 nm, directly applied to catalyst materials such as metal plates like TiO 2 , ZnO or MnO 2 [5,6]. Among them, TiO 2 is considered the most effective.…”

“…TiO 2 possesses strong photocatalytic properties, oxidizing and decomposing contaminants on surfaces and in the air. The process of UV radiation on these metal plates generates free radicals (OH -) and (O 2 -1 ), which exhibit strong oxidative capabilities [5]. These free radicals can oxidize volatile organic compounds (VOCs) in the air, as well as bacteria and mold, converting them into CO 2 and water [5].…”

TiO2 has a strong photocatalytic activity, which can oxidize and decompose impurities on surfaces and in the air. Therefore, TiO2 is used as an additive for the self-cleaning coating and paint industry. In this work, SiO2 is used in the TiO2/SiO2 mixture as the nucleus to homogenize the dispersion components. TiO2 and SiO2 nanoparticles are synthesized by sol-gel method combined with ultrasound that suits for the size range of 10-30 nm. The nano mixture is added to two green paint samples as Green Lable Paint EXT (exterior wall paint) and Green Lable Paint INT (interior wall paint) to replace antibacterial agents in paint formulations. In results, two paint samples showed antibacterial capability in accordance with ASTM D2574-06 for antibacterial paints.

“…Carballo et al 34 showed that the rutile/ anatase mixture led to a stronger interaction between the ruthenium species and the surface, preventing partially the catalyst sintering. Despite these considerable advances, a thorough understanding of the complicated mechanisms underlying the interaction of TiO 2 and the active phase is essential to exploiting its potential in applications ranging from environmental remediation to renewable energy production 19,[35][36][37][38] and remains an active research area. An accurate description of the electronic properties of TiO 2 provides insights into its band structure, energy levels, charge transfer mechanisms, and surface reactivity, which are crucial for predicting its behavior in various applications.…”

DFT functionals are of paramount importance for an accurate electronic and structural description of transition metal systems. In this work, a systematic analysis using some well‐known and commonly used DFT functionals is performed. A comparison of the structural and energetic parameters calculated with the available experimental data is made in order to find the adequate functional for an accurate description of the TiO2 bulk and surface of both anatase and rutile structures. In the absence of experimental data on the surface energy, the theoretical predictions obtained using the high‐accuracy HSE06 functional were used as a reference to compare against the surface energy values calculated with the other DFT functionals. A clear improvement in the electronic description of both anatase and rutile was observed by introducing the Hubbard U correction term to PBE, PW91, and OptPBE functionals. The OptPBE‐U4 functional was found to offer a good compromise between accurately describing the structural and electronic properties of titania.
