Title: Pore-Templated Growth of Catalytically Active Gold Nanoparticles within a Metal–Organic Framework

Abstract

Obtaining persistently well-dispersed gold nano-particles (AuNPs) on solid support with optimum particle size for heterogeneous catalysis can be challenging. Here, we report on the channel-templated growth of AuNPs within a stable zirconium-based metal–organic framework, NU-1000, via channel-anchored monometallic precursors. Pair distribution function analysis of total X-ray scattering by the incorporated face-centered-cubic nanopar-ticles reveals a bimodal size distribution, with ca. 98% of the en-shrouded nanoparticles having a diameter that closely reflects the ~10 Å width of triangular pores and with ca. 2% closely reflecting the ~31 Å width of hexagonal pores of NU-1000. The resulting ma-terial is catalytically active (and recyclable) for condensed-phase hydrogenation of 4-nitrophenol to 4-aminophenol.
