Synthesis and Characterization of Fe3O4-Ag Composite Nanoparticles for Oil–Water Separation

Synthesis of Fe3O4-Ag nanoparticles (NPs) was implemented via utilizing the method of coprecipitation for synthesizing the Fe3O4 nanoparticles, and reducing silver nitrate (AgNO3) to Ag nanoparticles, and impregnating the Ag NPs into the Fe3O4 NPs. The synthesized composite material was characterized using zeta potential, FT-IR, XRD, the contact angle, and the particles size distribution analysis.… Continue reading Synthesis and Characterization of Fe3O4-Ag Composite Nanoparticles for Oil–Water Separation

TiO2 ceramic membrane decorated with Fe3O4–Ag composite nanoparticles for produced water treatment

This study focused on the surface modification of commercial TiO2 membranes with Fe3O4 decorated silver (Ag) nanoparticles (Fe3O4–Ag) via chemical attachment. Firstly, the Ag concentration on Fe3O4 was optimized, and different composites were prepared and characterized. Secondly, the optimal composite was used to prepare novel TiO2/Fe3O4–Ag ceramic membranes via surface coating through tetraethyl orthosilicate (TEOS)… Continue reading TiO2 ceramic membrane decorated with Fe3O4–Ag composite nanoparticles for produced water treatment

Preparation of TiO2/SiO2 ceramic membranes via dip coating for the treatment of produced water

Produced water, a by-product generated from the oil and gas extraction processes, represents a major challenge in the oil and gas industry as it is generally characterized with a very high salinity and oil content. Currently used ceramic membranes for oil-water separation suffer from the low water flux in spite of their several distinctive advantages.… Continue reading Preparation of TiO2/SiO2 ceramic membranes via dip coating for the treatment of produced water
