Decoration of titania nanofibres with anatase nanoparticles as efficient photocatalysts for decomposing pesticides and phenols

Abstract

Using a series of partial phase transitions, an effective photocatalyst with fibril morphology was prepared. The catalytic activities of these materials were tested against phenol and herbicide in water. Both H-titanate and TiO(2)-(B) fibres decorated with anatase nanocrystals were studied. It was found that anatase coated TiO(2)-(B) fibres prepared by a 45 h hydrothermal treatment followed by calcination were not only superior photocatalysts but could also be readily separated from the slurry after photocatalytic reactions due to its fibril morphology.

Rapid microwave-assisted synthesis of sub-30 nm lipid nanoparticles

“…For food products, the color and appearance are crucial characteristics to consumers and depend on NP size[11], [12]. The importance of nanoparticle size can also be noted for catalysis[13, 14], pesticides[15, 16], and energy[17], [18] industries.…”

Photodegradation of Permethrin using Photocatalyst Montmorillonite-TiO2

“…Peaks on 2 at 25 and 48 confirmed this conclusion [10]. The formation of TiO2 Anatase was preferred on the reason that this phase is more photoactive then Rutile [6]. Ratio between Montmorillonite and TiO2 apparently affected proportionally to peaks detected by XRD instrument.…”

“…One of well-known photocatalyst material is Titanium Dioxide (TiO2). TiO2 has been used and developed for years through modification of shape, size and energy band gap [3,4,6].…”

“…[7]. Many efforts have been conducted on modification of TiO2 to provide optimum interaction between photocatalyst and pesticides [6,8]. Sol gels technique was used to synthesized TiO2 using surfactant to produced porous material along with large specific surface area [9].…”

“…Sol gels technique was used to synthesized TiO2 using surfactant to produced porous material along with large specific surface area [9]. Another researcher has been developed TiO2 photocatalyst using ultrasound agitation technique and hydrothermal treatment [6]. The reported TiO2 has Nano fibers structure and crystallite size; 10.16−17.9 nm.…”
