Co-Ti-O complex oxides: Hydrothermal synthesis, phase characterization, color analysis and catalytic activity assessment
© 2015, Chiang Mai University. All rights reserved. The hydrothermal synthesis of Co-Ti-O complex oxide nanoparticles from the reaction between TiO 2 and Co(NO 3 ) 2 .6H 2 O using the stoichiometric ratio to yield Co 2 TiO 4 and NaOH as mineralizer have been investigated. The particles were charac...

The hydrothermal synthesis of Co-Ti-O complex oxide nanoparticles from the reaction between TiO 2 and Co(NO 3 ) 2 .6H 2 O using the stoichiometric ratio to yield Co 2 TiO 4 and NaOH as mineralizer have been investigated.

Evidences on the pathogenic formation of Co 3 O 4 and CoTiO 3 are illustrated, and the unlikely in yielding a single phase of Co 2 TiO 4 is revealed. Detailed phase characterization is discussed. The particles showed a dark bluish green color, two different morphologies of rhombus and needle shape with a mean particle size of 150 nm, a remarkably narrow pore size distribution below 75 Å, and type II gas sorption behavior. An excellent performance as a catalyst toward the Fischer-Tropsch synthesis with 35% of CO conversion and a high selectivity toward the C 10 , has been revealed. 2018-01-24T04:45:54Z 2018-01-24T04:45:54Z 2015-01-01 Journal 01252526 2-s2.0-84946575859 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84946575859&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/44636 |
