摘要

本研究提出了一种新方法,通过引入氧化石墨烯 (GO) 沟槽层和应用氧化锌 (ZnO) 原子层沉积 (ALD),在 α 氧化铝中空纤维上制造 ZIF-8 膜。该方法成功地解决了一些关键难题,包括前驱体过度渗透和膜厚度问题。GO 层的引入和随后的氧化锌 ALD 处理大大降低了膜厚度,使其达到约 300 纳米,并消除了 GO 层和氧化铝支撑之间的分层问题。优化后的膜提高了丙烯的渗透率,其值约为不含 GO 的膜的三倍,并实现了更高的分离因子,表明结晶间缺陷最小。值得注意的是,GO 层影响了微观结构,导致渗透率随温度升高而增加。这些发现凸显了这种策略在开发用于气体分离应用的高性能 ZIF-8 膜方面的潜力。

Controlled Growth of ZIF-8 Membranes on GO-Coated α-Alumina Supports via ZnO Atomic Layer Deposition for Improved Gas Separation.

This study presents a novel approach for fabricating ZIF-8 membranes supported on α-alumina hollow fibers through the introduction of a graphene oxide (GO) gutter layer and the application of zinc oxide (ZnO) Atomic Layer Deposition (ALD). The method successfully addressed key challenges, including excessive precursor penetration and membrane thickness. The introduction of the GO layer and subsequent ZnO ALD treatment significantly reduced membrane thickness to approximately 300 nm and eliminated delamination issues between the GO layer and the alumina support. The optimized membranes demonstrated enhanced propylene permeance, with values approximately three times higher than those of membranes without GO, and achieved higher separation factors, indicating minimal inter-crystalline defects. Notably, the GO layer influenced the microstructure, leading to an increase in permeance with rising temperatures. These findings highlight the potential of this strategy for developing high-performance ZIF-8 membranes for gas separation applications.
