Abstract

A series of mesoporous composites of SO₄²⁻/Al-Zr/KIT-6, with varied ratios of ZrO₂ to Al₂O₃ and degrees of sulfation have been synthesized as an efficient, clean, facile and environmental-friendly nano-catalyst for the selective etherification of biomass-derived 5 hydroxymethylfurfural (HMF) to produce 5-ethoxymethylfurfural (EMF) as a biofuel candidate in a one pot process. Structure/property relationships of the catalyst have been determined and optimized in terms of EMF yield and HMF conversion. The resulting catalyst has been further tuned through tailored reaction conditions to produce an EMF yield of 89.8 % and HMF conversion of 99 %.
