4DescriptionAbstract A new Ag/Mo-MCM-41 mesoporous electrocatalyst with different weight ratio of Si to Mo (Si/Mo = 25, 50, 100 and 150) was prepared by direct hydrothermal (DHT) method. The synthesized Ag/Mo-MCM-41 was characterized by low angle x-ray diffraction (XRD) analysis, FESEM and FT-IR spectroscopy. The XRD of Ag/Mo-MCM-41 showed when incorporation of Mo into the MCM-41 matrix, the mesoporous structure is distorted slightly and hence the intensities are found to decrease with increase in Ag/Mo concentration. The morphological properties of the synthesized samples were studied by field emission scanning electron microscopy (FESEM) which shows the mesoporous electrocatalyst comprises of highly agglomerated particles. The FT-IR spectrum of the samples showed that the molybdenum was well incorporated within the MCM-41 frame work. The synthesized Ag/Mo-MCM-41 was used to modify glassy carbon electrode (GCE) and the modified electrode (Ag/Mo-MCM-41/GCE) was used to detect 4-chlorophenol (4-CP) in a pH 7.4 phosphate buffer solutions (PBS) by cyclic voltammetry (CV). At the Ag/Mo-MCM-41/GCE, 4-CP oxidized at lower positive potential with larger current response than the bare GCE. The proposed sensor exhibits great potential in the field of electrochemical detection of organic pollutant.
