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(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) (black). ntb = 4,4',4''-nitrilotrisbenzoate.
快速吸收
通过在室温下将{[Zn(3)(ntb)(2)(EtOH)(2)]4 EtOH}(n) (1) 浸入Pd(NO(3))(2)的乙腈溶液中，无需任何额外的还原剂，即可简单地制备钯纳米颗粒。与Zn(3)(ntb)(2)（黑色）相比，3 wt% PdNPs@1(NO(3)(-))(0.54)在77 K和1 bar以及298 K和高压下均显著提高了氢气吸收能力（见图，红色曲线）。ntb = 4,4',4''-次氮基三苯甲酸酯。
