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...

Chemical vapor deposition was employed to synthesize carbon nanotubes with Ni-loaded MCM-41 and MCM-48 as catalysts and acetylene as precursor at 750°C. Mesoporous Ni MCM-41 and Ni MCM-48 molecular sieves were synthesized by a hydrothermal method and were characterized by XRD and N2 adsorption isotherm. The catalytically synthesized carbon materials were characterized with Raman spectroscopy, N...

Manganese (?) complex with 2, 2? bipyridine, 1, 1? dioxide (bpdo) ligand was immobilized within nanoreactors of MCM-41. The immobilized complex was characterized by powder x-ray diffraction (XRD), nitrogen adsorption desorption, and FTIR. The pore volume, surface area and pore diameter of MCM-41 decreased after immobilization of Mn complex. Three bands observed at 1250, 1220 cm?1 and 757 cm?1 a...

Catalytic distillation is a technology that combines heterogeneous catalytic reaction and the separation of reactants products via in single reactor/distillation system. This process catalysis, kinetics, mass transfer to obtain more selective products. The catalyst provides sites for reactions porous surface liquid/vapor separation. advantages are energy savings, low waste streams, longevity, h...
