Abstract

By direct hydrothermal method, Mo-MCM-41 mesoporous catalysts with different Si/Mo ratio were prepared. Mo-MCM-41 was characterized by XRD, FT-IR, and DRS UV-Vis spectroscopy. The morphological property of the samples was characterized by SEM. The SEM images show the agglomeration of the particles. The synthesized Mo-MCM-41 was used to modify glassy carbon electrode (Mo-MCM-41/GCE). The detection of 4-chlorophenol (4-CP) using Mo-MCM-41/GCE in a pH 7.4 phosphate buffer solution (PBS) was carried out by cyclic voltammetry (CV). At the Mo-MCM-41/GCE, 4-CP is oxidized at less positive potential with larger current response than the bare GCE.
