Environmental implications and applications of engineered nanoscale magnetite and its hybrid nanocomposites: A review of recent literature

Wood-Biochar-Supported Magnetite Nanoparticles for Remediation of PAH-Contaminated Estuary Sediment

“…To address this issue, the electron-transfer reaction has been improved by using high-performance iron nanoparticles in the presence of SO 4 −• radicals in a manner similar to that of the Fenton reaction [8]. In this process, a suitable magnetic oxide (namely, iron oxide) and its composite are used for PS oxidation to yield an effective reactive species because iron oxide is a more effective and stable catalyst as compared to soluble Fe 2+ ions for the catalytic oxidation of organic pollutants [9][10][11]. Biochar is a readily available porous carbonaceous material that is produced as a solid by-product by the thermal decomposition of organic materials under oxygen-limited conditions and subsequent modification by chemical and physical methods [12].…”

Comparative Photocatalytic Degradation of Rose Bengal Dye under Visible Light by TiO2, TiO2/PAni and TiO2/PAni/GO Nanocomposites

“…Organic compounds such as halogeno-aliphatic hydrocarbons, halogeno aromatic hydrocarbons, organic acids, coloring matters, nitroaromatic hydrocarbons, substituted anilines, multi-ring aromatic hydrocarbons, hydroxybenzenes, surface active agents, and pesticides can be changed into non-toxic, decoloured inorganic compounds and ultimately eliminated as pollutants [6]. It is very interesting fact that TiO 2 absorbs only 5% UV portion of the solar light spectrum.…”

“…Rose Bengal is a significant xanthene dye and widely used in textile and photochemical industries whose molecular structure as shown in Figure 1. Rose Bengal shows the severe toxic effects on the human health and also affects the corneal epithelium [6]. It is very hazardous for the human being because it causes the irritation, itchiness, blistering and reddening.…”

Gas sensing properties of CuFe2O4 nanoparticles prepared by spray co‐precipitation method

“…Besides the conventional applications such as transformer cores in high frequency power supplies, microwave devices, high density magnetic recording etc, applications of these materials are diverging to new fields like medical diagnostics, site-specific drug delivery, magnetic refrigeration, ferrofluids and especially gas sensors. [1][2][3] Gas sensing properties of the ferrites was studied intensively over the last decade. Spinel ferrites such as NiFe2O4, CoFe2O4, MgFe2O4, CuFe2O4 etc were found to be sensitive to a wide range of gases including H2S H2O, CO, NH3 etc.…”
