title: Physicochemical properties and different sequence of metal loading (CuFe) over nanoporous of SUZ-4 zeolite.
abstract: Different sequence of Cu and Fe loading over nanoporous SUZ-4 zeolite were prepared by incipient wetness impregnation method. K/SUZ-4 zeolite was prepared with SiO2:Al2O3 molar ratio of 21.2 under hydrothermal process at 150 degrees C, 250 rpm for 1 day using tetraethylammonium hydroxide (TEAOH) as a template. Copper(II) and Iron(III) were loaded in K/SUZ-4 with 2.3 and 5.5 wt.% of Copper(II) and 1.0 and 5.0 wt.% of Iron(III). The physico-chemical characterization of CuFe/SUZ-4 were investigated using X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), BET-N2 adsorption, Scanning electron microscopy (SEM) and chemical element analysis. The results show the several types of sequential loading of Cu and Fe metals did not change the structure and pore size of nanoporous SUZ-4 zeolite. The obtained CuFe/SUZ-4 zeolites has a narrow pore size distribution with approximately 0.06 microm diameter with 0.66 microm length of needle crystal shape.
