Description:

Eco-friendly pillared montmorillonites, in which the pillars consist of iron oxide are expected to have interesting and unusual magnetic properties that are applicable for environmental decontamination. Completely “green” and effective composite was synthesized using mild reaction conditions and benign products. The composite was characterized by scanning electron microscopy (SEM) equipped with EDS, transmission electron microscopy (TEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA). Catalytic activity was tested against the degradation of dichlorophenol (DCP) and was found that in the presence of peroxymonosulfate, 85 % of DCP disappeared in 2.5 hours, whereas in the presence on hydrogen peroxide and peracetic acid, nearly 50% and 70% of DCP, respectively, degraded in 3.5 hours. TOC showed ca. 85% demineralization of the solution, which indicates a successful degradation of DCP.

Purpose/Objective:

Submitted for publication in American Chemical Society (ACS) Journal, ACS Sustainable Chemistry and Engineering as an invited article for a special issue on "Sustainable Nanotechnology"
