Modification the Band Gap of Nano Titanium Dioxide and Application Its Effectiveness on Photodegradation of 3- Methyl Phenol
Abstract
This study uses the sol-gel method to modify the band gap of titanium dioxide (anatase) by adding nitrogen atoms. By employing the sol-gel technique to modify the band gap of titanium dioxide (anatase), nitrogen atoms can be added. This will decrease the valence energy difference between the valence unit VB and the conduction band CB, facilitating the transfer of electrons from VB to CB. The formation of an (e-/h+) pair will be stimulated by the efficient absorption of photons of light equal to or greater than the line penetration energy. X-ray diffraction was used to determine the structure of the produced TiO2 grains, atomic force microscopy was used to determine the particle size and distribution, and ATR-FTIR and UV-Vis spectroscopy were used to analyze the photocatalytic repulsion. The resulting pair (e-/h+) will produce (˙OH) radicals, which can effectively remove organic contaminants from the surface of the photocatalyzed TiO2. The target load of the photocatalyst (TiO2) was (0.10 - 0.83 g/L) to supervise its implementation based on the analysis of 3-methylcarbolic acid (TiO2) before the specific water decomposition of the structure. The target load of (0.10 - 0.83 g/L) was to supervise its implementation based on the analysis of 3-methylcarbolic acid before the specific water decomposition of the structure. It was found that the most efficient pressure was directly proportional (0.43 g/L). The activities of titanium dioxide (octahydrate) and TiO2 drug with filling gas were directed under the control of an ultraviolet sky light source and explicit isolation presence according to the same standard. The height indicates that the aversion (primary command kinetics of the aversive mind) is 4.69 × 10⁻⁶ mins per 1 for TiO2 and 9.44 × 10⁻⁶ mins per 1 for oxygen-free TiO2. The ratio of command kinetics is constant at 4.69 × 10⁻⁶ mins per 1 for TiO2 and 9.44 × 10⁻⁶ mins per 1 for oxygen-free TiO2.
