“…The photocatalytic oxidation (PCO) using titanium dioxide is an efficient technology for the degradation of many pollutants [12,13,14,15]. It has also been known that the TiO2 shows the hydrophilicity due to the photocatalytic nature, the water tends to sheet across this surface rather than forming droplets [16]. This makes the surface anti-fogging and easily washable.…”

In the present work, titanium dioxide (TiO2) nanoparticles (NP’s) were prepared using sol-gel process from Titanium Tetrachloride (TiCl4) as a precursor with calcinations at two temperatures (500 and 900) °C. The effect of calcinations temperatures on the structural, optical, morphological and Root Mean Square (roughness) properties were investigated by means of Scanning Electron Microscopy, X-ray Diffraction (XRD), and Atomic Force Microscopy (AFM). Bacterial inactivation was evaluated using TiO2-coated Petri dishes. A thin layer of photocatalytic TiO2 powder was deposited on glass substrate in order to investigate the self-cleaning effect of TiO2 nanoparticles in indoor and outdoor applications. Ultra-hydrophilicity was assessed by measuring the contact angle and it evaluated photolysis properties through the degradation of potassium permanganate (KMnO4) under direct sunlight. XRD analysis indicated that the structure of TiO2 was anatase at 500 °C and rutile at 900 °C calcination temperatures. As the calcination temperature increases, the crystallinity is improved and the crystallite size becomes larger. Coated films of TiO2 made the has permeability, low water contact angle and good optical activity. These are properties essential for the application of the surface of the self-cleaning. The final results illustrate that titanium dioxide can be used in the build materials to produce coated surfaces in order to minimize air pollutants that are placed in microbiologically sensitive circumference like hospitals and the food factory.

“…Photocatalysts are used to purify air pollution caused by NOx, and titanium dioxide (TiO 2 ) is known to be the most effective material among various photocatalysts [4][5][6][7]. TiO 2 has better chemical stability than other photocatalysts and is not corroded by most acids, bases, and organic solvents, so it is actively used in various fields [8][9][10][11][12]. The application of TiO 2 in the construction field is being studied for application to large surface areas, such as the exterior of buildings and road pavements [13][14][15][16].…”

Nitrogen oxide (NOx), emitted at the highest rate among automobile exhaust gases, is the main cause of air pollution, and various construction technologies are being developed to reduce NOx emissions. In this study, the NOx reduction effect of surface treatment technology for road pavements, and the effect of the photocatalytic reaction on asphalt pavements, were evaluated using a photocatalyst. Three types of titanium dioxide (TiO2) were used as photocatalysts, and an asphalt rejuvenator used to recover aged asphalt was applied as a surface treatment agent. To evaluate the NOx reduction effect, a test device capable of testing large-sized specimens was manufactured and compared with the ISO method, which only allowed the testing of small specimens. In addition, the effect of TiO2 and the asphalt rejuvenator on the asphalt mixture was analyzed through chemical analysis. The test results of the newly manufactured mixed-tank photo reactor showed the same trend as the ISO test results concerning the evaluation of its NOx removal performance. As a result of the performance evaluation of the surface treatment using TiO2, the NO removal rate was up to 7.83% when Anatase-type TiO2 with excellent light efficiency was applied. In addition, when the rejuvenator was used, the oxidation of asphalt, caused by the photoreaction of TiO2, was reduced.

“…They are particularly sol-gel (Christian et al, 2016;Haider et al, 2018bHaider et al, , 2018c, co-precipitation, combustion (Xu et al, 2015), pyrolysis (Feng et al, 2012), polyol (Al-Douri et al, 2012), etc. These techniques have been used put together nano-structured metallic oxides utilised to electrodes for Li-ion batteries (Jameel et al, 2016). The chemical characteristic of cathode substances fundamentally up on the type of the structure, orientation of the planes and morphology of the substances attribute to various synthesis process.…”

LiNiCoO2 (LCNO) has been prepared using combustion method with urea as the igniter and glycerol as the binding material due to its high activity. Urea, used as fertiliser, can be produced by way of sequence chemical approaches by means of the usage of H2, N2 and CO2. It is good performance hydrogen and carbon dioxide as storage medium due to high energy density (16.9 M*J *L -1 , 10.1 weight percent of H2) for direct urea fuel cell (DUFC). Nitrates of Li + , Co +2 and Ni +2 had been combined together to shape a homogenous medium. Required quantities of urea and glycerol have been brought to combination and made a good paste. This paste is heated to 400°C for 2h. The as-synthesised fabric used to be subjected to thermo-gravimetric (TGA) analysis to decide the top of the line varies of annealing temperatures.
