Hierarchical SiO(2)@γ-AlOOH (Boehmite) core/sheath fibers are fabricated based on a combination of electrospinning and hydrothermal reaction. γ-AlOOH (Boehmite) nanoplatelets are uniformly anchored on the surface of SiO(2) fibers, which significantly improves the adsorption efficiency of the SiO(2) fiber membrane for organic dyes and microorganisms. Compared to conventional nanoparticle adsorbents, the self-standing membrane thus prepared is highly flexible and easy to handle and retrieve, making it a promising material for water treatment. By virtue of electrospinning and a hydrothermal reaction, it provides possibilities to fabricate other functional fiber membranes with hierarchical structures, which can find potential applications in adsorption, catalysis, filtration, and other environmental remediation fields.
基于静电纺丝和水热反应相结合的方法制备了分级 SiO(2)@γ-AlOOH（勃姆石）核/壳纤维。γ-AlOOH（勃姆石）纳米片均匀地锚定在 SiO(2)纤维表面，这显著提高了 SiO(2)纤维膜对有机染料和微生物的吸附效率。与传统的纳米颗粒吸附剂相比，所制备的自支撑膜具有高柔韧性、易于处理和回收的特点，是一种很有前途的水处理材料。借助静电纺丝和水热反应，为制备具有分级结构的其他功能纤维膜提供了可能性，这些纤维膜可在吸附、催化、过滤和其他环境修复领域找到潜在的应用。
