Abstract

TiO₂-supported Cobalt and cobalt-phosphorus catalysts prepared by impregnation are characterized by XRD, XPS, Laser Raman Spectroscopy (LRS), and Diffuse Reflectance Spectroscopy (DRS) and investigated in ethane oxidative dehydrogenation (ODH). At low cobalt loadings, the carrier is essentially covered by octahedral Co²⁺ ions, whereas at concentrations superior to 3.7 wt% formation of the Co₃O₄ spinel is observed. The best performance in ethane ODH is achieved at 550°C with the sample containing 7.6 wt% Co. The reaction begins with a conversion of 33% and a selectivity around 75%, then it decreases to reach after 150 min on stream a stationary state at 22% of conversion and 60% selectivity. This loss of 30% of the initial activity may be associated with a decrease of the specific surface area and the concomitant formation of CoTiO₃ and Co₂TiO₄, as revealed by LRS, in situ DRS, and XPS analysis. The activity in ethane ODH seems to be mainly related to the presence of Co²⁺ ions octahedral sites. Addition of phosphorus to Co(7.6)/TiO₂ catalysts results in the reduction of Co³⁺ ions and a growth of amorphous cobalt-phosphorus compounds which provoke a severe decrease of the catalyst performance.

At low cobalt loadings, the carrier is essentially covered by octahedral Co<sup>2+</sup>
 ions, whereas at concentrations superior to 3.7 wt% formation of the Co<sub>3</sub>
O<sub>4</sub>
 spinel is observed. The best performance in ethane ODH is achieved at 550°C with the sample containing 7.6 wt% Co. The reaction begins with a conversion of 33% and a selectivity around 75%, then it decreases to reach after 150 min on stream a stationary state at 22% of conversion and 60% selectivity. This loss of 30% of the initial activity may be associated with a decrease of the specific surface area and the concomitant formation of CoTiO<sub>3</sub>
 and Co<sub>2</sub>
TiO<sub>4</sub>
, as revealed by LRS, in situ DRS, and XPS analysis. The activity in ethane ODH seems to be mainly related to the presence of Co<sup>2+</sup>
 ions octahedral sites. Addition of phosphorus to Co(7.6)/TiO<sub>2</sub>
 catalysts results in the reduction of Co<sup>3+</sup>
 ions and a growth of amorphous cobalt-phosphorus compounds which provoke a severe decrease of the catalyst performance.</s0>
