Magnesium ferrite nanoparticles containing organic or inorganic support materials were preparated as heterogeneous catalysts. The characterization of the catalysts was performed by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), emission scanning electronic microscope/energy dispersive spectroscopy (SEM/EDS). Magnetic properties of the catalysts were determined by a vibrating sample magnetometer (VSM). Specific surface area and pore size distribution of the catalysts were obtained from nitrogen adsorption-desorption data at 77K by Brunauer-Emmett-Teller (BET) method.

Organik veya inorganik destek malzemeleri içeren magnezyum ferrit nanoparçacıklı heterojen katalizörler hazırlanmıştır. Katalizörlerin karakterizasyonu X-ışını toz kırınımı (XRD), Fourier dönüşümlü kızılötesi spektroskopi (FTIR), taramalı elektron mikroskop/enerji dağıtıcı spektroskopi (SEM/EDS) ile gerçekleştirilmiştir. Katalizörlerin manyetik özellikleri titreşimli örnek manyetometresi (VSM) ile belirlenmiştir. Katalizörlerin özgül yüzey alanı ve gözenek boyutu dağılımı, 77K'de azot adsorpsiyon-desorpsiyon verilerinden Brunauer-Emmett-Teller (BET) yöntemi ile elde edilmiştir.
