Abstract
In situ FTIR spectroscopy was used to study the interaction of pyridine-3-carbaldehyde (3PyA) with the surface of ТiO2 and a V-Ti-O catalyst in the temperature range of 120-300°C. 3PyA interacts with Lewis and Brönsted acid sites of ТiO2 and the V-Ti-O catalyst to form a nitrogen-coordinated complex and a s-bonded (through oxygen of the CHO group) complex, as well as a complex protonated at the N atom in the ring. Surface carboxylates (nicotinates) were also identified during the interaction of 3PyA with the V-Ti-O catalyst in the temperature range of 200-300°C.
