Quick on the uptake : Palladium nanoparticles were fabricated simply by immersing {[Zn 3 (ntb) 2 (EtOH) 2 ]⋅4 EtOH} n ( 1 ) in an MeCN solution of Pd(NO 3 ) 2 at room temperature, without any extra reducing agent. 3 wt % PdNPs@[ 1 ] 0.54+ (NO 3 − ) 0.54 significantly increase H 2 uptake capacities, both at 77 K and 1 bar and at 298 K and high pressures (see picture, red curve) compared to [Zn 3 (ntb) 2 ] n (black). ntb=4,4′,4′′‐nitrilotrisbenzoate.
