All used chemicals
and solvents are from Merck, Aldrich, and Fluke chemicals in this
work. The spectra of FT-IR were performed with pellets of KBr using
a Nexus 670 FT-IR spectrometer (Daypetronic Company, Tehran, Iran).
TL-chromatography was used to monitor the reaction over silica gel
plates. Particle morphology was investigated using a scanning electron
microscope (Daypetronic Company, Iran-Tehran) through FESEM-TESCAN
MIRA3. The 500 MHz spectra of 1H NMR and 13C
NMR were obtained using a spectrometer of BRUKER NMR (Daypetronic
Company, Iran-Tehran). Energy scattered X-rays of MNPS were
recorded using FESEM-TESCAN MIRA3 (Daypetronic Company, Tehran, Iran).
XRD was performed using Co radiation with a 40 kV wavelength scenting
P AD V X-ray (Beamgostar Taban Company, Tehran, Iran). The samples
were scanned in the ranges of 2θ = 1–10° and 2θ
= 10–80°; a BET isotherm of N2 was recorded
at 77 °K employing a standard gas manifold to explain the features
of materials like average pore diameter, pore-volume, and catalyst
surface (Daypetronic Company, Tehran, Iran). In addition, adsorption
data are presented in Brunauer–Emmett–Teller (BET) method.
In all reactions, CH3COOH with a molecular weight of 400
was applied. The content of Zn was measured by ICP-OES analysis (Tarbiat
Modares University, Tehran, Iran).
