| Summary: | A series of heterogeneous catalysts based on cobalt supported on SBA-15 were prepared through wet impregnation
and co-impregnation assisted by ethylene glycol (EG) methods. The cobalt oxide catalysts generated after the dry-
ing and calcination process were denoted as CoO/SBA-15w and CoO/SBA-15c for a wet- and co-impregnation method, respectively. Subsequent to the reduction process, the reduced cobalt catalysts were obtained and denoted as
Co/SBA-15w and Co/SBA-15c. The TEM images revealed the catalysts prepared through these methods show very clear distinctions that the catalyst prepared by wet impregnation shows large aggregates of cobalt particles on the external surface of SBA-15 due to their inability to enter the channels. The catalysts were evaluated on the hycellulose as a biomass model. The results showed that the reduced cobalt-based catalysts are having higher conversion value and selectivity towards the 2-furancarboxaldehyde reached ca. 20%.
