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 TiO2and Co(NO3)2.6H2O using the stoichiometric ratio to yield Co2TiO4and NaOH as mineralizer have been investigated. The particles were characterized by pow...

All rights reserved. The hydrothermal synthesis of Co-Ti-O complex oxide nanoparticles from the reaction between TiO2and Co(NO3)2.6H2O using the stoichiometric ratio to yield Co2TiO4and NaOH as mineralizer have been investigated. The particles were characterized by powder X-ray diffraction, selected area electron diffraction, scanning electron and transmission electron microscopies, UV-Vis, infrared and Raman spectroscopies, X-ray absorption near-edge spectroscopy, thermogravimetric analysis and gas sorption measurements. Evidences on the pathogenic formation of Co3O4and CoTiO3are illustrated, and the unlikely in yielding a single phase of Co2TiO4is 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 C10, has been revealed. 2018-09-04T10:09:11Z 2018-09-04T10:09:11Z 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/6653943832/54184
