A controlled, template-free, and hydrothermal synthesis route to sphere-like α-Fe₂O₃nanostructures for textile dye removal

Abstract

Iron carbonate nanospheres were synthesized via hydrothermal treatment of aqueous solutions of iron sulfate, ascorbic acid and ammonium carbonate with a molar ratio of 1 : 1 : 3, respectively, at 140 °C for 1.5 h.

A facile Pechini sol–gel synthesis of TiO2/Zn2TiO2/ZnO/C nanocomposite: an efficient catalyst for the photocatalytic degradation of Orange G textile dye

“…Orange G dye (OG)) are the most harmful dyes owing to the carcinogenicity and toxicity of the dyes because of the presence of azo groups (-N]N-) in their chemical structures. [4][5][6] Removal of contaminants from wastewater has become a crucial demand for humanity. Thus, many researchers have devoted much of their research work to the treatment of wastewater of the textile industries before the disposal process.…”

Green synthesis of zinc oxide nanoparticles using aqueous extract of Garcinia mangostana fruit pericarp and their photocatalytic activity

“…The discharge of dye effluents from various industries such as dye stuffs, textiles, paint and varnishes, inks, plastics, pulp and paper, food, rubber, and cosmetics to the environment is a prime cause of concern nowadays [1]. The effluents from these industries cause the water bodies not only to become coloured, but also lead to a reduction in sunlight penetration, decreasing photosynthetic activity, dissolved oxygen concentration and water quality; and having acute toxic effects on aquatic plants, causing severe environmental problems worldwide [2]. In addition, many synthetic dyes and their metabolites are toxic, mutagenic and carcinogenic [3].…”

Tunable auto-combustion preparation of TiO2nanostructures as efficient adsorbents for the removal of an anionic textile dye

“…The scientists found their way in nano-sized materials which have been regarded as an important type of adsorbent materials for the removal of heavy metals and organic pollutants from wastewater. 2,4,[20][21][22][23] However, reports on the removal of Reactive Red 195 (RR195) dye from wastewater are still limited. 2,20 Besides, searching for the most suitable nano-adsorbent is still a challenge.…”
