Advances and challenges of the spray drying technology: Towards accurately constructing inorganic multi-functional materials and related applications

Abstract

As an efficient, continuous and controllable particle preparation method, spray drying technology has shown unique advantages and broad application prospects in the synthesis and application of inorganic multi-functional materials. Through spray drying method, one can not only accurately regulate the composition and structure of material, but also can easily assemble nano-subunits into superstructures. This review first introduces the equipment composition and principle of spray drying technology. Subsequently, this review focused on the structure regulation and composition adjustment of inorganic multi-functional materials through spray drying technology. Finally, this review discusses the challenges and future development directions of spray drying in the preparation of inorganic multi-functional materials. Spray drying technology provides an efficient, flexible and controllable path for the synthesis of inorganic multi-functional materials. Its continuous technological innovation and application expansion will continue to promote the rapid development of related fields.
