In this paper a series of zirconium oxide supported on silica composite oxides were studied as catalysts for the production of 1,3-butadiene from bioethanol and acetaldehyde. The highest selectivity observed was 91.43%. Different silica materials with varied pore diameters in the range of 3.6–11.6 nm and the service life of the catalyst have been initially investigated. The catalysts were characterized by a nitrogen adsorption analysis, X-ray diffraction, scanning electron micrography and 29Si solid-state NMR spectroscopy. The catalytic results show that the pore sizes are important factors determining the activity when catalyst contains a subtle balance of the acid and base.
