Abstract

A recyclable catalytic system for the one-pot hydrolytic hydrogenation of xylan to xylitol has been developed. Phosphotungstic acid (PTA) and ruthenium were immobilized on covalent triazine frameworks (CTFs) to obtain a bifunctional catalyst which is capable of catalysing both hydrolysis and hydrogenation. PTA_Ru/CTF3 exhibits high activity with 88% xylan conversion and up to 80% selectivity to xylitol while its stability could be demonstrated over 6 recycling runs.
