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

“…Chinese researchers have reported a facile in situ growth process of SiO2@Fe3O4@MnO2, followed by an etching method to synthesize a hierarchical hollow structure, namely Fe3O4@MnO2 ball-in-ball hollow spheres (Fe3O4@MnO2 BBHs) for degradation of MB by catalytic generation of active radicals from peroxymonosulfate (PMS) [83]. A recent study reports fabrication of rationally-designed multicomponent nanocomposites comprising a magnetite core and an outer silver-decorated anatase shell and their application for visible-light hotodegradation of organic compounds [84].…”

Facile Synthesis of BiOBr/Bi2Sn2O7 Heterojunction Photocatalysts with Improved Photocatalytic Activities

“…Environmental pollution problems facing the world today have attracted much attention and are getting worse . Since Fujishima demonstrated the photocatalysis with TiO 2 under UV‐light irradiation in 1970s, semiconductor‐based photocatalytic technique has been considered to be one of the reliable and ultimate solutions to dealing with global environmental pollution .…”

CoMoO4 as a novel heterogeneous catalyst of peroxymonosulfate activation for the degradation of organic dyes

“…It is well known that reaction temperature is a critical operating parameter in AOPs, which can affect the degradation rate of organic pollutants greatly. [34][35][36] Date tting (Fig. 4a) shows that the reaction temperature also plays an important role in determining the degradation rate of MB.…”
