Degradation of methylene blue via photocatalysis of titanium dioxide

Photocatalytic degradation for methylene blue using zinc oxide prepared by codeposition and sol–gel methods

“…The equilibrium concentration of MB was used as the initial value for the photodecomposition processes. Some intermediates would be formed during methylene degradation, and the major absorption band of methylene blue and its degradation intermediates was around 665 nm [22][23][24]. In order to investigate the photocatalytic activities of ZnO-Si and ZnO-C, the mineralization of methylene blue was evaluated according to the absorption change in this work.…”

Fabrication and characterization of neat and aluminium-doped titanium (IV) oxide fibers prepared by combined sol–gel and electrospinning techniques

“…Other than these properties, it has been known to be an excellent photo-catalyst for the decomposition of various organic substances that include certain pesticides [3]. This pertains titania as excellent candidate for the treatment of agricultural waste water [4]. Titania is known to have three natural polymorphs, i.e., rutile, anatase, and brookite.…”

Synthesis and photocatalytic property of SnO2/TiO2 nanotubes composites

“…It has been reported that TiO 2 with higher specific surface area demonstrated a better photocatalytic performance than the simple TiO 2 particles [10]. Therefore, it is of great interest to find a special technique that enables the photocatalyst with higher specific surface area to decompose pollutants with high reaction rate and may be easily applied to industry.…”
