Ba doped on CeO2-δ supported MnOx catalyst for selective oxidation of alcohol to aldehyde

Metal Ion Migration: A New Insight into the H+/O2– Dual-Ion Transport in Perovskite–Fluorite Composites

“…More et al prepared barium-doped MnO x /CeO 2−δ catalysts. The distortion of the ceria lattice in their result was attributed to the Ba doping into the Ce lattice . In this work, the same phenomenon can be found, and, accordingly, the shift of the fluorite peak can be ascribed to partial Ba incorporation into the fluorite lattice.…”

The role of WOx and dopants (ZrO2 and SiO2) on CeO2-based nanostructure catalysts in the selective oxidation of benzyl alcohol to benzaldehyde under ambient conditions

“… 51 More and co-workers reported barium-doped MnO x /CeO 2− δ catalysts for the solvent-free oxidation of benzyl alcohol to benzaldehyde using TBHP, with enhanced selectivity for benzaldehyde (55.3%) compared to the Mn 0.5 /Ce 0.5 catalyst. 52 Akinnawo et al addressed the deficiency in heterogeneous catalysis by utilizing inverse micelles as nanoreactors to design mesoporous Ce x Zr 1− x O 2 , with varying Zr composition, and then systematically analysed the catalysts. Notably, the formula Ce 0.8 Zr 0.2 O 2 showed superior performance in the oxidation of benzyl alcohol with TBHP.…”

The catalytic activity of Pd/CeO 2 in the solvent-free and atmospheric-pressure conversion of benzyl alcohol to benzaldehyde was achieved with high efficiency, showing 72.6% conversion and 92.3% selectivity under specic reaction conditions.…”

Low temperature oxidation of CO using alkali- and alkaline-earth metal-modified ceria-supported metal catalysts: a review

“…Thus, it is obligatory to develop a systematic perspective to improve low temperature CO oxidation. Alkali acts as an electron promotor to enhance the surface redox properties and is responsible for the low temperature CO and VOC oxidation [31][32][33][34]. The CO oxidation activity of noble metal and NM supported on ceria was enhanced by addition of AM and AEM [35][36][37][38].…”
