Three-dimensional mesoporous carbon aerogels: ideal catalyst supports for enhanced H(2)S oxidation.

Impregnated mesoporous carbon aerogels serve as novel catalysts for the first time with respect to low-temperature oxidation of H(2)S to elemental sulfur, and exhibit particularly high activity (up to 3 g sulfur per gram of catalyst) and high selectivity.
