CU-CE modified Mesoporous Silica with magnetic core preparation characterization and catalytic application

Using the surfactant CTMA Br (Cetyltrimethylammonium bromide) and cerium(IV-cupper ) sulfate,mesoporouscu- Ce-MCM-41 molecular sieves were produced under a hydrothermal condition with various surfactant/silica (surfactant/Si) and silica/cerium (Si/Ce-cu) ratioto the structural traits caused by changing the molar ratios of both surfactant/Si and Si/Ce-cu were investigated. SEM (scanningelectromicroscopy) were used for the characterization of prepared mesoporous samples..Among the tested molar ratios, surfactant/Si-cu ratio of 1/60 and 1/90 showed highest values of d100and intensity, respectively, for the Si-MCM-41Rod-like shapewith rounded edges of the prepared Ce-MCM-41 samples was identified by SEM. These results suggest surfactant/Si ratio of -Si/Ce-Cu1/60 and 1/90and Si/Ce ratio of 60 and Si/Cu ratio of 90 for the production of Cu- Ce-MCM-41 with the highest level of Si/Ce-cu crystallinity
