“…A combination like that is able to combine polymeric features, which include low weight and easy formability, with the unique property of the chosen inorganic particles. Additionally, the insertion of polymer and more precisely polyethylene glycol has been proved that it can reduce the possibility of a cracking on the deposition of thin lm, it can decrease the size of nanoparticles and increase the porosity and photocatalytic ability of the catalyst [53].…”

The introduction of eco-friendly nanomaterials capable of addressing environmental challenges in industrial applications has gained wide attention and encouraged strong collaborations between science and the public and private sectors. WHO and many governmental health organizations have highlighted the environmental and human health effects caused by exposure to nitrogen oxides (NOx) and especially nitrogen dioxide (NO2). Vast research has highly investigated the adverse effects on human health after exposure to NO2 and has profoundly recommended its mitigation in the emissions of various sources. This study proposes the development of a novel bioclimatic product in the form of a “green”, eco-friendly tile, with photocatalytic properties, able to degrade atmospheric pollutants, for subsequent use in roof tiles. To this aim, novel “green” roof tiles were developed based on the deposition of various crystallographic types of titanium dioxide (TiO2) and the addition of two polymeric materials onto their upper surface. Experiments were conducted using nanoparticles of TiO2 anatase, rutile, and a mixture of them along with the addition of Polyethylene glycol and Pluronic F-127. All types of newly developed nanomaterials were characterized using X-Ray diffraction analysis (XRD), particle size distribution analysis, the Brunauer-Emmet-Teller (BET) method, and Scanning electron Microscopy (SEM). Commercial ceramic roof tiles underwent spray-coating techniques, using the novel nanoparticles, followed by the investigation of their photocatalytic performance. The TiO2 anatase samples with the addition of PEG exhibited the greatest specific surface area among all types of samples, thus indicating their high photocatalytic efficiency, which was also proved by subsequent photocatalytic experiments for the tiles sprayed with the same type of nanoparticles. The results reported in this study indicate that the novel cool and eco-friendly roof tiles prove to be ideal for the enhancement of environmental protection, the mitigation of air pollution and greenhouse gas emissions, and the reduction of the urban heat island phenomena.

“…In recent years, researchers have developed TiO 2 nanoparticles for photo-sensing [25], photoelectrochemical [26], a new material for the environment [27], self-cleaning, and solar cell [28]. These applications based on the high unique properties TiO 2 like inert and high-stability in physicochemical, but in application TiO 2 needed the material doping for delivering the high-stability electron transfer in the system [29][30][31][32].…”

The unique study of TiO 2 sol-gel modified carbon paste electrode (CPE) nanocomposites have been developed for electrochemical sensor detecting fipronil pesticide compound. We develop the easy synthesized TiO 2 via a sol-gel method and modified in CPE which applied electrochemical system as cyclic voltammetry (CV) because the concentration is proportional with current peaks. We discover the TiO 2 optimal mass used of 0.1 g which is compared with 0.7 g carbon and 0.3 mL paraffin. It has high-current anodic (Ip a) of 1.13×10 3 μA and high-current cathodic (Ip c)-0.96×10 3 μA in scan rate of 0.5 V/s. The limit of detection (LOD) of fipronil has been determined of 34.0×10-5 μM in percent recovery of 0.8%. Its high-stability for lifetime TiO 2-CPE nanocomposites was expressed for 13 days which mean that can be used for detecting fipronil pesticide.

“…Therefore, an appropriate method for obtaining FeTiO 3 as a model of natural ilmenite is to synthesize FeTiO 3 using sol-gel method. The sol-gel method is one of the most effective methods to modify materials so it will produce new materials and new properties with size under 100 nm [17]. Chen [18] has synthesized FeTiO 3 using sol gel method with particle size of 20 to 60 nm that potentially as photocatalyst material for methylene blue dye adsorption.…”

Preparation of ilmenite (FeTiO3) composite for antimicrobial under UV-visible lights irradiation was carried out to appropriate as a new antimicrobial material. The preparation of FeTiO3 by using sol-gel method was conducted by the titanium tetra-isopropoxide (TTIP) as precursor titania and added Fe(NO3)3 as Fe source. Subsequently, the antimicrobial test (Escherichia coli, Staphylococcus aureus and Candida albicans) was carried out under photocatalysis system. The FeTiO3 was formed on 2θ of 20°, 24°, 36°, 48°, 53° and 62° having crystal size 53.75 nm. Scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) was investigated that the particle sized was under 100 nm and Fe element peak was on 6.398 keV. The antimicrobial test showedthat the efficiency of 15 % FeTiO3 was active under visible light irradiation to inhibit of E. coli, S. aureus and C. albicans with diameter zone were 18.778, 19.889 and 20.22 mm, respectively.
