Rhodamine B (RhB) in dyes is widely used various industries, but it poses a great threat to the natural environment and human health. In this work, series of thermosensitive polymer materials, PNxDy, with controllable morphology particle size were prepared by free radical polymerization using N-isopropylacrylamide N,N-dimethylacrylamide as monomers. Then, PNxDy template, bimetallic Mn- Co-doped...

In this study MCM-41, Fe20-MCM-41 and Fe40-MCM-41 mesoporouse silicates have been prepared in various conditions with cetyltrimethylammonium bromide (C16) and dodecyltrimethyl-ammonium chloride as template and various mole ratios of Si/Fe. The resulted compositions have been characterized by power X-ray diffraction, N adsorption–desorption measurements and Fourier transform infrared spectroscop...

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...
