摘要: Abstract A novel class of nanostructured silicious materials MCM-41 type containing cobalt, CoO x /MCM-41, and exhibiting remarkable long-range self-organized morphology has been developed. The method synthesis is a one step procedure includes the use poly-acrylic acid, complexed with CTAB by zip-type mechanism, as backbone structure. On external surface this mesostructure, hydrolysis TEOS Co(NO 3 ) 2 takes place at various pH values. loading cobalt (9 /MCM-41 was determined in range 910–1250 m /g nitrogen porosimetry their pore volume 0.7–0.9 cm /g. diameter D found to be around 3.1 nm while anisotropy b = L / , where —the length pores, 15–380 depending on sample.
