Summary: This study explored the effect of different water matrices on the photocatalytic degradation of dissolved pharmaceuticals. The degradation efficiencies in wastewater effluent and water effluent were compared with deionized water. The results showed that even in the presence of other organic molecules, the compounds could still be removed from the water, although at a slower rate. Understanding the effects of different wastewater compositions on photocatalytic reactions can help refine the potential applications of this technology.

Summary: The study investigates the effects of Cr and N doping on the properties of TiO2 anatase nanoparticles, including adsorption capacity, photocatalytic performance, and antibacterial response. Doping with Cr and Cr/N enhances adsorption capacity and photocatalytic performance, with Cr-TiO2 nanoparticles exhibiting antibacterial activity under visible light. The differences in electrostatic charge and nanoparticle dispersion are suggested as the main reasons for the varied antibacterial response among the doped nanoparticles.

Summary: The environmental impact of industrial technologies and related remediation methods is a significant research area. In the development of materials for wastewater treatment or air purification, the use of hazardous reactants often diminishes the overall positive contribution to the environment. This study presents the synthesis of stable titanium dioxide (TiO2) sols using an environmentally friendly method. The sol was deposited on glass and evaluated for wastewater purification ability by photocatalytic degradation of organic dyes. The results showed high efficiency and reusability, with degradation rates exceeding 85% for Rhodamine B and 100% for Methylene Blue.

Summary: Cu and Y co-doped TiO2 nanoparticles were prepared using an acid-catalytic sol-gel process, resulting in a single anatase phase with reduced crystallite size. SEM observations showed uniform nanospheres being synthesized under the proposed conditions. XPS results demonstrated the presence of Cu+ and Y3+ ions. The photoactivity of the co-doped TiO2 was improved due to effective separation of electron-hole pairs, increased formation of active radicals, and increased surface area.

Summary: This study investigated the effect of the mixing ratio of TiO2 nanoparticles (P25) and titanium alkoxide (T-sol) on various properties of TiO2 films. The specific surface area, microstructure, thickness, transmittance, pencil hardness, and oil contact angle of the films were analyzed. The results showed that the specific surface area increased as the P25 content increased, but this effect decreased as the ratio of T-sol to P25 increased. The thickness, surface roughness, transmittance, pencil hardness, and oil contact angle of the films were also affected by the P25 content, with increased thickness and surface roughness, decreased transmittance and pencil hardness, and decreased oil contact angle.

Summary: The sol-gel coprecipitation method is a convenient and affordable synthesis method for bismuth-doped TiO2 photocatalysts. Effective doping improves the photoactivity of the catalyst, enabling effective electron excitation under visible light. Different doping percentages of bismuth can modulate the photocatalytic response and provide engineered control over the semiconductor's bandgap energy. 5% doping provides the optimal balance of photocatalytic properties and effectiveness in treating the model organic pollutant indigo carmine (IC).

Summary: Obtaining photocatalytic coatings on textile materials is challenging due to the conflicting properties that need to be achieved. This study proposes a solution using hybrid silica films generated by sol-gel processes, containing TiO2 sensitized with iron (III) phthalocyanine (FeTCPc). The coatings were made using a pad-dry-cure process with various agents. Experimental results show that treatment with BORAX improves the resistance of the coatings to wet treatments but impairs their photocatalytic performances.

Summary: In this study, graphene nanoplatelets (GnP)-modified epoxy polymer nanocomposites with different concentrations were developed using two processing techniques. The results showed that ultrasonication enabled better exfoliation of graphene sheets, resulting in higher electrical conductivity at lower filler concentrations. Thermal conductivity, on the other hand, was mainly affected by the restacking of graphene sheets. Additionally, effective thermal and electrical conductivity models were defined to predict the performance of nanocomposites at different loadings. The optimized nanocomposite was successfully embedded into a carbon fiber laminate composite to enhance its properties.
