AB Acetylation of glycerol to yield monoacetin (MAT), diacetin (DAT), and triacetin (TAT) overNiO-supported CeO2 (xNiO/CeO2) catalysts is reported. The catalysts were synthesized utilizing asol-gel technique, whereby different quantities of NiO (x = 9, 27, and 45 wt%) were supported ontothe CeO2 substrate, and hexadecyltrimethylammonium bromide (CTABr) served as a porogen. Theutilization of EDX elemental mapping analysis confirmed the existence of evenly distributed Ni2+ion and octahedral NiO nanoparticles on the CeO2 surface through the DRS UV-Vis spectroscopy.The most active catalyst is 27NiO/CeO2 based on TAT selectivity in the glycerol acetylation withethanoic acid, attaining 97.6% glycerol conversion with 70.5% selectivity to TAT at 170  C with a 1:10glycerol/ethanoic acid molar ratio for 30 min using a non-microwave instant heating reactor. The27NiO/CeO2 is reusable without significant decline in catalytic performance after ten consecutivereaction cycles, indicating high structure stability with accessible active acidity.
