Immobilization of Cu(II)-Histidine Complex on Al-MCM-41 as Catalyst for Epoxidation of Alkenes

Cu(II) complex with L-histidine (His) ligand, immobilized within Al-MCM-41, designated as Cu(His)2/Al-MCM-41 was prepared and characterized by powder X-ray diffraction (XRD), nitrogen adsorption desorption, FTIR, UV-Vis and chemical analysis techniques. The surface area and pore volume were found to decrease after immobilization of Cu(II) complex on Al-MCM-41. It was found that Cu(His)2/Al-MCM-...

Immobilization of Candida rugosa lipase on MCM-41 for the transesterification of cotton seed oil.

Present study demonstrated the preparation of MCM-41 as a support for the immobilization of Candida rugosa lipase by the physical adsorption technique. The lipase immobilized MCM-41 has been characterized by scanning electron microscopic and FTIR techniques. At pH 6, maximum lipase immobilization (250 mg/g) on MCM support has been observed and the immobilized lipase was employed as biocatalyst ...

Immobilization of a molybdenum complex with tetradentate ligand on mesoporous material MCM-41 as catalyst for epoxidation of olefins

Covalent grafting of MCM-41 with 3-chloropropyl trimethoxysilane and subsequent reaction respectively with acacdien and complexation with MoO2(acac)2 afforded MoO2acacdien@MCM-41. X-ray diffraction and nitrogen sorption analyses revealed the preservation of the textural properties of the support as well as accessibility of the channel system despite sequential reduction in surface area, pore vo...

immobilization of cu(ii)-histidine complex on al-mcm-41 as catalyst for epoxidation of alkenes

cu(ii) complex with l-histidine (his) ligand, immobilized within al-mcm-41, designated as cu(his)2/al-mcm-41 was prepared and characterized by powder x-ray diffraction (xrd), nitrogen adsorption desorption, ftir, uv-vis and chemical analysis techniques. the surface area and pore volume were found to decrease after immobilization of cu(ii) complex on al-mcm-41. it was found that cu(his)2/al-mcm-...

Synthesis Characterization and Catalytic Evaluation of Mesoporous Fe-MCM-41 and Si-MCM-41 Materials

Environmental concern associated with safe handling disposal of corrosive mineral acids such as HF have encouraged the development of safer and non waste producing alternative for application in catalysis. In this sense ,mesoporous materials attracted much attention of catalysis to transform big molecules into its useful products. In the present study we have synthesized, mesoporous Fe-MCM-41an...
