A simple ‘in situ’ co-precipitation method for the preparation of multifunctional CoFe₂O₄–reduced graphene oxide nanocomposites: excellent microwave absorber and highly efficient magnetically separable recyclable photocatalyst for dye degradation

Abstract

Here, an ‘in situ’ co-precipitation reaction method has been reported for the preparation of CoFe2O4–RGO (CF–RGO) nanocomposites.

Sulfur-doped CoFe2O4 nanopowders for enhanced visible-light photocatalytic activity and magnetic properties

“…11,13 Therefore, it is considered as potential photocatalyst in eliminating various organic pollutants. 14,15 Among these materials, CoFe 2 O 4 attracts more attention due to its moderate magnetic performance at room temperature and good chemical stability. 16 It is oen composited with other semiconductor materials such as TiO 2 , WO 3 and C 3 N 4 , or conducting materials such as graphene, oxidized graphene and carbon nanotube, in order to improve the photocatalytic degradation performance.…”

Graphene Oxide: An Efficient Carbocatalyst for the Facile Synthesis of Isoindolo[2, 1‐a]quinazoline‐5,11‐diones via Domino Condensation under Solvent‐Free Conditions

“…For both cases decomposition behavior was almost similar and a total weight loss of ∼45% was observed till 500 °C (ESI Figure S2). The powder XRD pattern of GO showed a sharp diffraction peak at 2θ=11.5° and a small intensity peak at 42.54° which correspond to (001) and (101) planes respectively of GO (Figure ) . The presence of oxygen containing functional groups (like carboxyl, epoxy and hydroxyl) on the surface of GO was confirmed from FTIR study.…”

Membrane‐Solvothermal Synthesis of Cobalt Ferrite/Reduced Graphene Oxide Nanocomposites and Their Photocatalytic and Electromagnetic Wave Absorption Properties

“…In recent years, there are all kinds of visible and invisible pollution around us in our daily life . The organic water pollution, a kind of visible pollution, has posed gigantic threats to the ecological environment and people's life . However, the invisible electromagnetic pollution can not only adversely affect electronic equipment, but also interfere with human health .…”

“…[1] The organic water pollution, a kind of visible pollution, has posed gigantic threats to the ecological environment and people's life. [2][3][4][5] However, the invisible electromagnetic pollution can not only adversely affect electronic equipment, but also interfere with human health. [6] Therefore, the preparation of multi-functional materials has great significance to reduce environmental pollution.…”
