Role of Ba($ O_{2} $)1−x$ O_{x} $ species in improvement of selective oxidation activity of $ CoO_{x} $/$ CeO_{2−y} $
Abstract A series of Ba-doped $ CoO_{x} $/$ CeO_{2−y} $ catalysts was prepared by co-precipitation followed by the deposition–precipitation method. The catalysts were investigated for selective oxidation (selox) of benzyl alcohol (B-ol) using tertiary butyl hydroperoxide (TBHP) without solvent and a...

| 520 | |a Abstract A series of Ba-doped $ CoO_{x} $/$ CeO_{2−y} $ catalysts was prepared by co-precipitation followed by the deposition–precipitation method. The catalysts were investigated for selective oxidation (selox) of benzyl alcohol (B-ol) using tertiary butyl hydroperoxide (TBHP) without solvent and activity was compared with $ Co_{0.5} $/$ Ce_{0.5} $. The Ba loading has been optimized with time and temperature for selox reaction. The catalyst was characterized by various surface and bulk characterization techniques. The characterization study indicates that the synergistic interaction between Ba and CoCe could form more oxygen vacancies and peroxide species responsible for the activation of B-ol and TBHP. The formation of Ba($ O_{2} $)1−x$ O_{x} $ oxide (peroxide) was observed and could be responsible for the activation of B-ol. The optimum Ba doping enhances selectivity and yields benzaldehyde. However, the increase in Ba concentration on $ CoO_{x} $/$ CeO_{2−y} $ could lead to the over-oxidation of B-ol to by-products. | ||

Role of Ba($ O_{2} $)1−x$ O_{x} $ species in improvement of selective oxidation activity of $ CoO_{x} $/$ CeO_{2−y} $ |
| abstract |
Abstract A series of Ba-doped $ CoO_{x} $/$ CeO_{2−y} $ catalysts was prepared by co-precipitation followed by the deposition–precipitation method. The catalysts were investigated for selective oxidation (selox) of benzyl alcohol (B-ol) using tertiary butyl hydroperoxide (TBHP) without solvent and activity was compared with $ Co_{0.5} $/$ Ce_{0.5} $. The Ba loading has been optimized with time and temperature for selox reaction. The catalyst was characterized by various surface and bulk characterization techniques. The characterization study indicates that the synergistic interaction between Ba and CoCe could form more oxygen vacancies and peroxide species responsible for the activation of B-ol and TBHP. The formation of Ba($ O_{2} $)1−x$ O_{x} $ oxide (peroxide) was observed and could be responsible for the activation of B-ol. The optimum Ba doping enhances selectivity and yields benzaldehyde. However, the increase in Ba concentration on $ CoO_{x} $/$ CeO_{2−y} $ could lead to the over-oxidation of B-ol to by-products. © Indian Academy of Sciences 2020 |
