An inorganic silicate zeolite material and its viral filtration applications

By controlling the synthesis conditions of modified hydrogen-type zeolite and the use of dispersing additives, uniform distribution of aluminum atoms is achieved, increasing the acid site density of zeolite. Hydrogen ions are used to form hydrogen bonds with viral surface proteins to inactivate viruses, solving the problems of poor biocompatibility and low inactivation efficiency of existing antiviral materials, and achieving a highly efficient virus inactivation effect.

AI Technical Summary

Technical Problem

Existing antiviral materials have poor biocompatibility and low inactivation efficiency, making them unable to effectively kill airborne viruses, especially the novel coronavirus (SARS-CoV-2). Furthermore, traditional metal-based zeolite materials suffer from cytotoxicity and high cost.

Method used

By controlling the synthesis conditions of modified hydrogen-type zeolite, adding dispersing additives and ultrasonic treatment, the uniform distribution of aluminum atoms in the zeolite framework is achieved, thereby increasing the ion exchange capacity and acid density. Hydrogen ions are used to form hydrogen bonds with viral surface proteins to achieve chemical inactivation of the virus.

Benefits of technology

An inorganic silicate zeolite material with high efficiency in inactivating viruses has been obtained. It has extremely strong surface acidity and high biocompatibility, and can safely and effectively kill viruses in the air, especially the novel coronavirus. It is suitable for antiviral gauze, masks and air purification filters.

Abstract

本发明公开一种无机硅酸盐沸石材料及其病毒过滤应用。本发明通过加入特定的分散添加剂并进行超声处理，使氢型沸石的铝原子均匀分布在沸石结构中。同时结合控制氢型沸石的合成条件，控制其孔道大小、硅铝比以及粒径大小，极大提升沸石骨架的离子交换容量和酸密度。调控后的沸石经过离子交换后氢离子含量高，因此得到的氢型沸石具有极强的表面酸性，可对病毒产生强烈的化学作用。氢型沸石的酸性位点会与病毒表面蛋白的碱性基团形成稳定的氢键，从而可迅速锚定病毒并使其迅速失活，达到灭活病毒的效果。本发明旨在解决现有抗病毒材料灭活效率低、生物相容性差的问题，特别针对空气传播病毒等具有高效的灭活效果，并具有优异的生物安全性。
