本项目提出了一种有效迁移纳米催化剂至膜孔表面制备高分子催化分离膜的新方法。通过蒸汽诱导相分离形成聚合物富相和贫相，由于颗粒布朗运动和两相界面处的能阱，纳米催化剂颗粒会迁移并固定在两相界面上，最终形成膜孔表面均布纳米催化剂颗粒的高分子催化分离膜。拟重点研究纳米催化颗粒有效迁移至膜孔表面的影响因素与规律、纳米催化剂的加入对贫相生长的影响及膜孔形成的规律、以及制备所得的高分子催化分离膜的催化性能以及跨膜传质行为，探明膜孔结构的形成和纳米催化颗粒在膜孔表面分布的可控规律、以及高分子催化分离膜的精细微观物理/化学结构与其分离催化性能的可控性规律。研究结果将为高分子催化分离膜的可控制备提供新途径和必要的理论基础。

In this project, we propose a novel strategy to fabricate polymeric catalytic membranes with effective migration of nanocatalysts to the membrane pore surface. Via the vapor-induced phase separation, due to the introduction of water vapor, phase separation occurs in the membrane-forming solution containing nanocatalysts to form polymeric phase and aqueous phase. Based on the Brownian motion of nanocatalysts and energy-trapped theory at the interfaces, once the nanocatalysts migrate to the interface between polymeric phase and aqueous phase, they would be trapped. Finally, the polymeric catalytic membranes with nanocatalysts loading on their pore surfaces are prepared. This work focuses on the effect factor and regularity of the migration of nanocatalysts to the pore surface, the growth of the aqueous phase and formation of the pore structure affected by the addition of nanocatalysts, the catalytic performance and permeability of the proposed polymeric catalytic membranes. The influences of pore structure and the distribution rule of nanocatalysts on pore surface will be studied. The physical/chemical microstructure as well as catalytic and separation performances of the polymeric catalytic membranes will be investigated systematically. The research results will provide new strategy and essential theoretical basis for controllable fabrication of polymeric catalytic membranes.
