Many energetic applications could benefit from the peculiar morphology of aerogel materials. Their large specific surface area combined with a tunable pore size distribution make them particularly appropriate for most catalytic processes. TiO2 aerogels have thus advantageously been developed in our group respectively for hydrogen production by water splitting and hydrogen conversion in fuel cells.
