Biomass valorization derivatives: Clean esterification of 2-furoic acid using tungstophosphoric acid/zirconia composites as recyclable catalyst

- Tungstophosphoric acid/zirconia composites catalysts are green and active catalyst.
- The catalysts were found active, stable, recyclable and reusable.
- Alkyl 2-furoates were synthesized with a 100% of selectivity.
- We described a green procedure in solvent-free condition for biomass valorization.
- The esterification procedure contributes to the waste minimization.
