建立了一种简便的原位金属前体掺入策略,以良好地控制金属纳米颗粒在金属有机框架(MOFs)内的位置和组成。这种一步金属前体掺入路线成功地应用于制备超细Pd、Ni和PdNi合金,以选择性地封装在MOFs的孔内,在硝基苯加氢中实现上级催化活性和稳定性。
A facile, in situ metal precursor incorporation strategy is established for good control over the location and composition of metal nanoparticles within metal-organic frameworks (MOFs). This one-step metal precursor incorporation route is successfully applied to the fabrication of ultrafine Pd, Ni, and PdNi alloys to be selectively encapsulated inside the pores of MOFs, achieving superior catalytic activity and stability in the hydrogenation of nitrobenzene.
