Abstract
Converting mineral raw materials into porous materials represents an effective and high-value approach. Among these materials, porous geopolymers made from metakaolin (whether natural or synthetic) have garnered significant attention. This review comprehensively explores the methods for introducing pore structures, porous properties, and applications of metakaolin-based porous geopolymers (MPGs). Additionally, it discusses the future development prospects of this field. By summarizing and analyzing research progress, this review aims to provide a comprehensive understanding of the current status of metakaolin-based porous geopolymers research. It highlights innovative foaming routes to achieve desired porous structures, enhance specific properties, and expand or tailor applications. Ultimately, this study aims to stimulate further research and application of bulk-type or shaped porous geopolymers using metakaolin as a raw material, particularly in the field of water purification and pollutant removal.
期刊介绍：
Applied Clay Science aims to be an international journal attracting high quality scientific papers on clays and clay minerals, including research papers, reviews, and technical notes. The journal covers typical subjects of Fundamental and Applied Clay Science such as:
• Synthesis and purification
• Structural, crystallographic and mineralogical properties of clays and clay minerals
• Thermal properties of clays and clay minerals
• Physico-chemical properties including i) surface and interface properties; ii) thermodynamic properties; iii) mechanical properties
• Interaction with water, with polar and apolar molecules
• Colloidal properties and rheology
• Adsorption, Intercalation, Ionic exchange
• Genesis and deposits of clay minerals
• Geology and geochemistry of clays
• Modification of clays and clay minerals properties by thermal and physical treatments
• Modification by chemical treatments with organic and inorganic molecules(organoclays, pillared clays)
• Modification by biological microorganisms. etc...
