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.

磷酸修饰CaNb2O6的Lewis酸催化木糖脱水制糠醛†

采用无定形金属配合物法制备了磷酸修饰的CaNb2O6，并对其作为木糖脱水制糠醛的固体催化剂进行了试验。正交CaNb2O6由八面体NbO6和方反棱镜体CaO8组成，具有独特的Lewis和Brønsted酸位。这些活性位点比正交Nb2O5具有更高的糠醛产率。
