Ruthenium-titanium oxide aerogel catalyst, method for preparing the same, and method for hydrogenation and hydrodeoxygenation using the same

A catalyst for hydrogenation and/or hydrodeoxygenation reaction, consisting of a mixed metal oxide of ruthenium (Ru) and titanium (Ti),

• wherein the catalyst is in a form of a metal oxide aerogel produced by supercritical drying, and
• wherein the catalyst is obtained by mixing nitric acid with an alcohol, adding a titanium precursor, and stirring to obtain a mixture;
• adding an alcohol solution containing a ruthenium precursor to the mixture and stirring, followed by adding water to obtain a wet gel;
• subjecting the wet gel to supercritical drying to obtain an aerogel;
• and calcining the aerogel.
