TiO2-Pt aerogel composites have been synthesized by mixing sol-gel titania with Pt colloidal suspensions followed by supercritical drying. The highest specific surface achieved with these materials ranged between 550 and 600m2g-1 before annealing and stayed relatively high; i.e; 162m2g-1; after calcination. The concentration of Pt nanoparticles ranged between 0.3 and 1.0wt.% while their size ranged between 5.75 and 6.5nm. These composites were employed as photocatalysts for room-temperature photocatalytic reforming of ethanol and hydrogen production. The highest hydrogen production rate; 7.2mmolH2h-1g-1; was obtained in the case of the smallest and most concentrated metal nanoparticles underlying the importance of the number of active sites on the TiO2-Pt composites. This rate of hydrogen production is relatively high and reflects the relatively high specific surface of the employed photocatalysts. © 2013 Elsevier B.V;
