Abstract:
CeO2 nanorods and nano-octahedra exhibit divergent surface intermediate dynamics during CO2 carboxylation with ethylene glycol, as revealed by in situ synchrotron infrared spectroscopy. CeO2 nano-octahedra outperform nanorods in catalytic activity. Time-resolved carbonate/CH2 coverage ratio studies reveal that nano-octahedra sustain active catalytic turnover, while nanorods' surface sites are blocked by bridged alkoxides.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
