| Outline of Final Research Achievements |
Various nanoporous metals including Au, Pd, Cu, AuPd have been fabricated and their nanoporous structures were characterized by SEM, TEM, HRTEM, EDX, and BET. The nanoporous gold proved to be an excellent heterogeneous catalyst in oxidation of alcohols and organosilanes, selective reduction of alkyne, quinoline, imine, aldehyde, and ketone, selective diborylation of and hydrosilylation of alkynes, dehydrogenative cross-coupling of α-C(sp3)-H of amines, and benzannulation. Moreover, the nanoporous-Pd catalyst is a promising heterogeneous catalyst for the Suzuki coupling and Heck reaction. The nanoporous copper catalyst exhibited a distinct nanosize-dependent catalytic activity in the Click reaction of the terminal alkynes and organic azides. Interestingly, the AuPd alloy nanoporous catalyst showed a remarkable synergistic effect for the heterogeneous 1,4-hydrosilylation of conjugated cyclic enones with organosilane in comparison with nanoporous monometallic catalysts.
