Summary:The influence of synthesis and post-synthesis procedures of different niobium oxides on their catalytic performance in the aqueous phase condensation of oxygenated compounds is studied. Hydrothermally synthesized niobium oxide with a pseudo-crystalline structure shows enhanced acid properties, surface area and consequently better catalytic activity than Nb 2 O 5 prepared by other synthesis methods. The optimized NbO x -based catalyst also demonstrates higher stability after several reuses compared to the Ce–Zr mixed oxide reference catalyst.
