A novel scheme to fabricate polybenzimidazole (PBI) hollow fiber membranes with a thin skin loaded with fully dispersed palladium nanoparticles is proposed for the first time. Palladium is added to the membrane during the spinning process in the form of ions that coordinate to the imidazole groups of the polymer. This is attractive for membrane production because agglomeration of nanoparticles is minimized and the high‐cost metal is incorporated in only the selective layer—where it is required. Pd‐containing membranes achieve three orders of magnitude higher H2 permeances and a twofold improvement in H2/CO2 selectivity compared to pure PBI hollow fiber membranes.

用于氢纯化的聚苯并咪唑/钯纳米粒子中空纤维膜的制备
首次提出了一种新颖的制备具有薄皮的聚苯并咪唑（PBI）中空纤维膜的方案，该膜负载了完全分散的钯纳米颗粒。钯在纺丝过程中以与聚合物的咪唑基团配位的离子形式添加到膜中。这对膜生产很有吸引力，因为可以最大程度地减少纳米颗粒的团聚，并且仅在需要的情况下将高价金属仅掺入选择性层中。与纯PBI中空纤维膜相比，含Pd膜的H 2渗透率提高了三个数量级，并且H 2 / CO 2选择性提高了两倍。
