Abstract
Preparation, characterization and catalytic test for glucose conversion of Co3O4/NiFe2O4 catalyst has been studied. Preparation of catalyst involved several steps including mixing, evaporating, impregnating, and calcination. Characterization of the catalyst involved identification of acid sites using spectrophotometry methods, crystalline phases using X-ray diffraction, and morphology of the catalyst surface using scanning electron microscopy. Furthermore, catalytic tests on glucose conversion reaction were done by varying both temperature of reaction (80 and 90 oC) and time of reaction (30 and 60 minutes) and the product was analyzed by high performance liquid chromatography (HPLC). From characterization tests, it is shown that Lewis acid sites are relatively more pronounced than Bronsted – Lowry acid sites. Diffractogram analysis revealed that catalyst consisted of Co3O4, NiFe2O4, and NiO crystalline phases. Based on the results of catalytic test, it is concluded that catalyst is active to convert glucose into fructose at temperature of 80 and 90 oC and reaction times of 30 and 60 minutes. Its activity reached 90% of glucose conversion, but selectivity is still relatively low.
