|Chao Miao, Lixing Liang, Shumei Chen, Kaixuan Shang, Yi Zhang, and Jing Ouyang, A brief review on fabrication and application of porous materials from silicon-rich industrial solid waste, Int. J. Miner. Metall. Mater.,(2021). https://doi.org/10.1007/s12613-021-2360-9|
Porous materials have many promising prospects in such fields as sound insulation, heat barrier, vibration attenuation, and catalysts, due to their special porous structures. Most of the industrial solid wastes such as tailings, coal gangue, and fly ash are rich in silicon. As far as this is concerned. In this regard, the high silicon content makes it a potential raw material for the synthesis of silicon-based multi-porous materials such as zeolites, mesoporous silica, glass ceramics, geopolymer foams, etc. In this mini review, the representative silicon-rich industrial solid wastes (SRISW) are selected as the objects, which focused on the processing and application of silicon porous materials from the aspects of physical and chemical properties of SRISW. The transformation methods of preparing porous materials from silicon rich industrial solid wastes are summarized, and their research status in micro-, meso-, and macro-scale porous materials are concluded, respectively. Also the possible problems existing in the application of silicon-rich industrial solid wastes, and in the preparation of functional porous materials are analyzed, and their developing orientation is prospected. This review should provide a typical reference for the recycling and utilization of industrial solid wastes to develop some sustainable “green materials”.
