(a) A reverse double-solvent approach has been developed for encapsulating metal clusters inside the cavities of cage 6 (Figure 3). (b, c) HAADF-STEM Images and (d) particle size of the obtained Pd clusters. The Pd@6 showed excellent catalytic activities for (e) hydrogen generation from ammonia borane, (f) hydrogenation of 4-nitrophenol, and (g) reduction of dyes.
