摘要
An effective solvent-free method based on a solid-reduction process was developed to fabricate ultrafine gold catalysts. By this method we revealed a strong size-dependent activity of Au species in which subnanometer-sized clusters exhibited the best activity in the hydrogenation of CO_2 to formate, with a turnover number of up to 9278 over 7 h at 90 ℃.
