ABSTRACT
MCM-41 modification with Cr cation was carried out by direct synthesis using of the
surfactant templating process and the impregnation method. The produced molecular
sieves were characterized by XRD, FTIR spectroscopy and N2 adsorption-desorption.
All prepared materials acquired a typical MCM-41 structure. The prepared samples
were tested in the photocatalytic degradation of 3-chlorophenol in aqueous medium.
The reactants and products were analyzed using high performance liquid
chromatography (HPLC) and ion chromatography (IC). The data obtained indicate
that the structure modifications of MCM-41 affected not only the activity of MCM-41
for the disappearance of chlorophenol but also for the degradation intermediates.
