“…In this region, absorption band is affected by Fe 2 O 3 polymorph. In general, the polymorphs of FeOOH can be dehydrated to Fe 2 O 3 form under the influence of either heat or mechanical stress and the product of the dehydroxylation of FeOOH form is meghemite [16,19,20]. The iron oxide gel (Fig.…”

Alumina supported 5% Co catalyst was prepared, by the controlled nanocrystal deposition method using oleic acid as a capping agent, and tested for its activity and selectivity in Fischer-Tropsch synthesis. The catalyst exhibited facile reducibility of the cobalt species. The CO conversion and C 5? selectivity obtained on this size-controlled catalyst were higher than those observed on the catalysts prepared by impregnation and precipitation techniques. Decrease in the mobility of the nanoparticle towards the tetrahedral sites of alumina could be the reason for high reducibility, as the formation of cobalt aluminate was found to be considerably reduced during temperature programmed reduction.

“…Iron (III) oxide (Fe 2 O 3 ) materials have four phases: ␣-Fe 2 O 3 (hematite); ␤-Fe 2 O 3 ; ␥-Fe 2 O 3 (maghemite); and -Fe 2 O 3 [3]. The nanocrystals of magnetic ␥-Fe 2 O 3 have been applied in information storage, magnetic refrigeration, bioprocessing, controlled drug delivery, and ferrofluids [4][5][6], while ␣-Fe 2 O 3 is environmentally friendly and has been used for gas sensor, lithium ion battery, catalyst and pigment applications [7][8][9].…”
