Photocatalytic Degradation Mechanism of Malachite Green under Visible Light Irradiation over Novel Biomimetic Photocatalyst HMS-FePcs

Characterization and photocatalytic properties of TiO$_{2}$/chitosan nanocomposites synthesized by hydrothermal process

“…The mixture became transparent and colorless, suggesting that degradation at these levels results in complete mineralization. 41,42 This is probably due to the fact that low light intensity reactions involving electron-hole (e − /h + ) formation are predominant and electron-hole recombination is negligible. However, as the light intensity increased, so did the light electron-hole recombination, which caused the reaction rate to decrease.…”

A facile route to synthesis of S-doped TiO2 nanoparticles for photocatalytic activity

“…With population growth expected to increase by 40-50% over the next 50 years, combined with industrial urbanisation, there will be an increasing demand for water resulting in serious environmental consequences [11]. Wastewater from chemical industries contain large quantities of highly toxic and hazardous pollutants which is one of the most serious concerns to the aquatic environment [12]. Many dyes in the textile and printing industry are toxic and carcinogenic in nature and a representative of an increasingly global problem [13,14].…”

“…Due to the limitations of TiO 2 such as band gap width, many studies have focused doping TiO 2 and using various other photocatalysts to decompose malachite green from wastewater [22][23][24][25]. Gao et al [26] used HMS-FePcs to successfully decompose MG in the presence of H 2 O 2 . It was noted that the solution became increasingly acidic as the degradation of MG increased.…”

Decolorization of Methylene Blue withTiO2Sol via UV Irradiation Photocatalytic Degradation

“…The organic solvent slowed down the hydrolysis rate of tetrabutyl titanate and then decreased the photocatalytic activity of TiO 2 [22]. It also resulted in more serious environmental pollution [23,24]. To overcome the disadvantages, the use of aqueous solution instead of organic solvent was desired.…”
