Abstract
Phosphate-modified CaNb2O6 was prepared using the amorphous metal complex method and tested as a solid catalyst for xylose dehydration to furfural. The orthorhombic CaNb2O6 consists of octahedral NbO6 and square antiprismatic CaO8, providing unique Lewis and Brønsted acid sites. These active sites exhibited a higher furfural yield compared to orthorhombic Nb2O5.
