Evaluating the sensitizing effect on the photocatalytic decoloration of dyes using anatase-TiO2

Enhanced visible light photocatalytic activity and mechanism of ZnSn(OH)6 nanocubes modified with AgI nanoparticles

“…Moreover, most of the dyes and their degradation products may be carcinogenic and toxic to mammals [3,4]. Conventional chemical and biological treatment can remove dye from wastewater but seem to be not satisfied because of higher energy consumption and generation of toxic by-products [5,6].…”

Nanostructured N-doped TiO2 coated on glass spheres for the photocatalytic removal of organic dyes under UV or visible light irradiation

“…Each year, it is estimated that 12% of synthetic textile dyes such as indigo red, rhodamine B, methylene blue (MB), eriochrome black-T (EBT) and methyl orange (MO), are lost during manufacture and processing operations, and 20% of these lost dyes enter into the environment through effluents derived from the treatment process of industrial wastewaters. With increasing synthetic dyes usage, dye removal from wastewater becomes an important but challenging area of research since most of dyes and their degradation products may be carcinogenic and toxic to mammals [4,5].…”

Novel biosynthesized silver nanoparticles from cobweb as adsorbent for Rhodamine B: equilibrium isotherm, kinetic and thermodynamic studies

“…Multi-walled carbon nanotube (Yang and Xing 2010), MgO (Li et al 2012;Mahmoud et al 2015), chitosan-zinc oxide (Salehi et al 2010), zero-valent iron (Satapanajaru et al 2011), silver (Satapathy et al 2013), gold (Xu, 2010), NiO (Samiey and Farhadi 2013), TiO 2 (Hsiao et al 2014;Lyu et al 2014) nanoparticles have been employed in wastewater purification and have proved to be faster in action and more effective in performance. Also, catalytic degradation of dyes has been achieved using nanoparticles (Bogireddy et al 2015;Han et al 2013;Kumari and Philip 2015;Lateef et al 2016a, b, c;Ojo et al 2016;Oladipo et al 2017).…”
