 Abstract
This paper presents our investigation on the synthesis and characterization of Mn-MCM-41. Three catalysts with different total metal loading were prepared. The synthesized mesoporous materials were characterized using several techniques, such as: nitrogen physiosorption, UV-VIS spectroscopy, transmission electron microscopy and temperature programmed reduction (TPR). The aim of our investigations was to study the influence of the structure of the catalytic centers (Mn ions) on their oxygen release capacity.

 Rezumat
În această lucrare sunt prezentate rezultatele experimentale în ceea ce priveşte sinteza şi caracterizarea Mn-MCM-41. Au fost preparate trei şarje de catalizatori cu diferite concentraţii de metal înglobare respectiv 1wt%, 2wt% şi 3wt%. Materialele mezoporoase au fost caracterizate prin: reducere programată de temperatură, adsorbţie fizică, spectroscopie UV-VIS si TEM.
