Abstract
The present disclosure provides a preparation method of an efficient and stable catalytic membrane based on a multi-scale hollow molecular sieve fiber, and belongs to the technical field of molecular sieve preparation. The preparation method includes the following steps: mixing a silicon source, an aluminum source, water, and an organic template, and stirring; heating, and adding deionized water; conducting a reaction by hydrothermal synthesis; conducting centrifugation on an obtained suspension, loading by mixing an obtained powder free of a mother liquor with an iron source, and washing and drying; dissolving a treated powder in anhydrous ethanol and conducting an ultrasonic treatment; adding a surfactant to an obtained dispersion, stirring, and conducting the ultrasonic treatment; and conducting coaxial electrospinning and calcination in sequence to obtain the membrane based on a hollow molecular sieve fiber.
