Preparation and Evaluation of Manganese Catalysts of Alumina and Mesoporous Silica Mesh (HMS) (Mn / Al2O3, Mn / HMS) and their Catalytic Activity in Liquid Phase

In this paper Mesoporous silica catalyst (HMS) are prepared and (5%-7.5%-10%-15%) weight of differentsalts of manganese (Nitrate manganese,acetat,solfat,chloride)by impregnation method. It has been observed that themanganese nitrate salt has the highest percentages. This catalyst is used in the reaction of cyclohexane oxidation tocyclohexanone and cyclohexanol. Has been The results are investigated using FT-IR analysis and X-ray diffraction(XRD) techniques, and the size of particles is determined using the Shereh equation.scanning electron microscope(SEM) also confirms the morphology of the mesoporous structure and changes in morphology after the placement ofmanganese salt on the base.
