Enhanced Hydrogen Storage by Palladium Nanoparticles Fabricated in a Redox-Active Metal-Organic Framework

Quick on the uptake: Palladium nanoparticles were fabricated simply by immersing {[Zn₃(ntb)₂(EtOH)₂]·4 EtOH}n (1) in an MeCN solution of Pd(NO₃)₂ at room temperature, without any extra reducing agent. 3 wt % PdNPs@[1]⁰.⁵⁴⁺(NO₃ ⁻)₀.₅₄ significantly increase H₂ uptake capacities, both at 77 K and 1 ba...

Zusammenfassung:Quick on the uptake: Palladium nanoparticles were fabricated simply by immersing {[Zn₃(ntb)₂(EtOH)₂]·4 EtOH}n (1) in an MeCN solution of Pd(NO₃)₂ at room temperature, without any extra reducing agent. 3 wt % PdNPs@[1]⁰.⁵⁴⁺(NO₃ ⁻)₀.₅₄ significantly increase H₂ uptake capacities, both at 77 K and 1 bar and at 298 K and high pressures (see picture, red curve) compared to [Zn₃(ntb)₂]n (black). ntb=4,4',4''-nitrilotrisbenzoate.
