Synthesis of Mesoporous Iron Oxides by Citrate Sol-Gel Method. II. Morphological Characteristics Control
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 2
Abstract
The mechanism of mesoporous maghemite g-Fe2O3 by thermal decomposition of iron citrate hydrate was investigated and the influence of sol-gel synthesis conditions on its morphological characteristics was studied. It was shown that the gelation process in aqueous solution of iron citrates monomers depends on pH level of reaction medium. Thermal decomposition of iron citrate xerogels allows to obtain the mesoporous maghemite with predictable specific surface area and pore size distribution.
