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.

Atomically Precise Growth of Catalytically Active Cobalt Sulfide on Flat Surfaces and within a Metal–Organic Framework via Atomic Layer Deposition

Journal Article Peters, Aaron W. ; Li, Zhanyong ; Farha, Omar K. ; ... - ACS Nano

Atomic layer deposition (ALD) has been employed as a new synthetic route to thin films of cobalt sulfide on silicon and fluorine-doped tin oxide platforms. The self-limiting nature of the stepwise synthesis is established through growth rate studies at different pulse times and temperatures. Additionally, characterization of the materials by X-ray diffraction and X-ray photoelectron spectroscopy indicates that the crystalline phase of these films has the composition Co ₉S ₈. The nodes of the metal–organic framework (MOF) NU-1000 were then selectively functionalized with cobalt sulfide via ALD in MOFs (AIM). Spectroscopic techniques confirm uniform deposition of cobalt sulfide throughout themore »« less

Immobilizing Highly Catalytically Active Pt Nanoparticles inside the Pores of Metal-Organic Framework: A Double Solvents Approach

Journal Article Aijaz, Arshad ; Karkamkar, Abhijeet J. ; Choi, Young Joon ; ... - Journal of the American Chemical Society

Ultrafine Pt nanoparticles were successfully immobilized inside the pores of a metal-organic framework MIL-101 without deposition of Pt nanoparticles on the external surfaces of framework by using a 'double solvents' method. The resulting Pt@MIL-101 composites with different Pt loadings represent the first highly active MOF-immobilized metal nanocatalysts for catalytic reactions in all three phases: liquid-phase ammonia borane hydrolysis; solid-phase ammonia borane thermal dehy-drogenation and gas-phase CO oxidation. The observed excellent catalytic performances are at-tributed to the small Pt nanoparticles within the pores of MIL-101. 'We are thankful to AIST and METI for financial support.

Adsorption of a catalytically accessible polyoxometalate in a mesoporous channel-type metal–organic framework

Journal Article Buru, Cassandra T. ; Li, Peng ; Mehdi, B. Layla ; ... - Chemistry of Materials

A Keggin-type polyoxometalate (H ₃PW ₁₂O ₄₀) was incorporated into a mesoporous Zr-based MOF (NU-1000) via an impregnation method in aqueous media, resulting in the hybrid material, PW ₁₂@NU-1000. The POM@MOF composite was characterized by a suite of physical methods, indicating the retention of crystallinity and high porosity of the parent MOF. The hybrid material was also stable to leaching in aqueous media at varying pH. Lastly, the material was tested as a heterogeneous catalyst for the oxidation of 2-chloroethyl ethyl sulfide using hydrogen peroxide as the oxidant. PW ₁₂@NU-1000 was shown to have a higher catalytic activity than eithermore » of the individual constituents alone.« less

Peroxide-treated metal-organic framework templated adsorbents for remediation of high level nuclear waste

Journal Article Gilhula, James C. ; Patterson, Jacob T. ; Williams, Neil J. ; ... - Journal of Hazardous Materials

Remediation of legacy nuclear waste is one of the greatest challenges faced by the US Department of Energy, with projected cleanup efforts requiring over five decades and hundreds of billions of dollars. New materials are necessary to accelerate waste processing, achieving time and financial savings. Herein we report a peroxide treatment to a Ti metal-organic framework (MOF) and related MOF-templated adsorbents. Furthermore, the resulting materials displayed exceptional affinity for Am(III), achieving distribution coefficients in excess of 10 ⁵ mL/g, and out-performing state-of-the-art benchmarks monosodium titanate (MST) and peroxo-treated modified MST (mMST) for removal of ⁸⁵Sr(II) and ^{239, 240}Pu(IV) from legacymore » nuclear waste simulant.« less
