Ethanol conversion was carried out on two MgO catalysts that differ in concentration of surface basic sites by a factor of 4. The sites density was increased by chemical densification of MgO-aerogel that created high-angle grain boundaries defect areas between its nanocrystals. This process using the novel catalytic material converted ethanol in one step to biofuel containing C 5+ paraffins, olefins, aromatics and oxygenates with about 50% yield. This improved performance was attributed to enhanced trapping of hydrogen entities formed at the surface after dissociative adsorption of alcohols molecules at the defect sites produced by densification.
