Mesoporous molecular sieves for indoor air purification: Adsorption and catalysis

The demand for a high-quality indoor environment where individuals spend most of their time is rapidly increasing in line with promoting life-quality standards. Indoor air pollution primarily originates from chemical gases emitted by various building materials and home goods, as well as pathogenic microbial aerosols emitted from garbage and ventilation equipment. Both adsorption and catalysis methods are extensively employed to purify indoor air pollutants. As a typical porous material, mesoporous molecular sieves have attracted significant attention as adsorbents or catalyst carriers for pollutant adsorption and degradation due to their large specific surface area, tunable pore structure, and ease of surface modification. This communication discusses the development of mesoporous molecular sieve-based adsorbents, catalysts, and antibacterial materials for indoor pollutant removal. It provides a detailed overview of the selection and optimization of various mesoporous molecular sieves, including pore structure regulation and surface modification, to enhance their effectiveness as air purification materials (adsorbents/catalysts/antibacterial agents). Furthermore, by analyzing and summarizing the current research progress and existing challenges in this field, this review aims to provide valuable insights for researchers in related areas.
