摘要：
An ensemble cast: The confinement of ensembles of Au-Pd inside unique mesoporous TiO2 spheres contributes to their superior photocatalytic activity. Direct spectroscopic evidence reveals that the addition of palladium could suppress the growth of gold nanoclusters and prolong the lifetime of the excited electrons on these nanoclusters, thereby resulting in enhanced photoactivity.
