Gold in nano-crystal size is known as highly active CO-oxidation catalyst. Using simple deposition techniques gold has been deposited as $3 nm particles inside the channels of mesoporous silica-TiO 2 -MCM-48. In the presence of gold nano-particles the catalyst converts CO to CO 2 at 50% level at ร20
