Enhancement of Adsorption Efficiency of Methylene Blue on Co3O4/SiO2 Nanocomposite

Single and well-crystalline Co3O4 phase imbedded in an amorphous SiO2 matrix has been obtained by novel aqueous solution method. The structural and morphological properties are investigated using X-ray diffraction, Fourier transform infrared spectrometer, and N2 adsorption–desorption techniques. The...
