Abstract
New manganese silicate denoted as MnKIL-1 was prepared by two-step synthesis.
Solvothermal treatment
in ethanol in the second step of the synthesis gave rise of a disordered
mesoporous silicate structure with the
pore openings of 16 nm. The mesoporous property (porosity) of the new material
was investigated by employing
powder X-ray diffraction (XRD), transmission electron microscopy (TEM) and
nitrogen sorption.
UV-Vis diffuse reflectance spectroscopy results suggested that the Mn2+ and Mn3+
cations were coordinated
in the mesoporous silicate structure in the disordered octahedral and
tetrahedral environments, respectively.
