MnFe2O4 nanoparticulate obtained by microwave-assisted combustion: An efficient magnetic catalyst for degradation of malachite green cationic dye in aqueous medium

Photocatalytic activity and magnetic properties of Ba2FeMoO6 ferromagnetic double perovskite

“…The textile industry generates large amounts of waste-water, which has harmful effects and seriously threatens human health and the environment. Since some of these dyes are non-degradable, they can block sunlight and potentially stop the photosynthetic process [ 1 ]. In the past, most dyes used in industry were natural, i.e., derived from animals and plants.…”

“…The dye triphenylmethane, known as malachite green (MG), is used in the textile, paper, and leather industries [ 1 ]. Also, it is a therapeutic agent to treat and prevent fungal and parasitic infections [ 3 ] in fish.…”

“…Currently, many physical, chemical, biological, and electrochemical methods, such as adsorption and visible light degradation, are used to remove toxic dyes. These techniques have varying degrees of success [ 1 , 4 ]. Among all these methods, the adsorption method is one of the most suitable methods for absorbing organic pollutants from water because of its low cost, simple operation, environmental friendliness, and wide range of applications.…”

“…Among all these methods, the adsorption method is one of the most suitable methods for absorbing organic pollutants from water because of its low cost, simple operation, environmental friendliness, and wide range of applications. Andrade et al [ 1 ] used H 2 O 2 /MnFe 2 O 4 to remove the MG dye from aqueous effluents in 60 min without changing the pH of the solution. Muinde et al [ 4 ] reported that 1.2 g of CS–ZnO material removed malachite green from aqueous media with an adsorption rate of 93.6 % in 180 min.…”

Fabrication of a recyclable magnetic halloysite-based cobalt nanocatalyst for the efficient degradation of bisphenol A and malachite green

“…12 A plethora of methodologies are enlisted in the literature for the removal of BPA and MG, but these approaches encountered serious drawbacks such as lesser degradation efficiency, prolonged reaction time, harsh conditions and catalyst retrievability and reusability, which restrict their large-scale practical applicability. 13–34 Therefore, a great array of endeavours need to be dedicated towards the fabrication and exploration of new catalytic materials, which not only overcome the abovementioned challenges but also meet the criteria of green chemistry. 35–37 In this regard, engineered halloysite nanotube-based nanocomposites have recently emerged at the forefront as excellent heterogeneous catalytic systems.…”
