Abstract

This study investigates the catalytic conversion of 5-hydroxymethylfurfural (HMF) into 5,5-(Oxybis(methylene))-bis-2-furfural (OBMF) using graphene oxide (GO) and metal-doped graphene oxide catalysts (GO-Ce, GO-Ce-Fe, GO-Ce-Ni). The catalysts were synthesized using a Tour's method and characterized through FTIR, XRD, SEM, and TEM, confirming effective Ce doping and cerium oxide nanoparticle dispersion on GO. The GO-Ce catalyst achieved a maximum OBMF yield of 97% at 140°C over 12 hours. GC-MS and NMR analyses validated the high conversion efficiency of OBMF. Comparative studies showed GO-Ce's superior selectivity and stability over other catalysts.
