Graphene oxide-mesoporous delta-MnO2 nanocomposite as a novel destructive sorbent

Popis výsledku v původním jazyce

A graphene oxide-mesoporous birnessite-type δ-MnO2 nanocomposite (GO-MnO2) was prepared by thermal hydrolysis of suspension potassium permanganate (KMnO4), 2-chloroacetamide and with graphene oxide (GO) in aqueous solution. The prepared nanocomposites samples were characterized by Brunauer–Emmett–Teller surface area (BET) and Barrett–Joiner–Halenda porosity, X-ray Diffraction (XRD), high-resolution scanning electron microscopy (HRSEM) and high-resolution transmission electron microscopy (HRTEM) with energy dispersive x-ray spectroscopy (EDS) for create the map of elements. The degradation activity of the prepared samples was assessed from the kinetics of the stoichiometric degradation of parathion methyl (PM) in the polar solution (acetonitrile). It was shown that prepared samples were effective in decomposition of PM by cleavage of the P-O-aryl bond in the pesticide molecule. The degradation mechanism for PM on the GO-MnO2 surfaces was proposed.
