托贝莫来石的晶体结构、合成改性及吸附应用现状OA

Tobermorite(TOB)is a layered calcium silicate hydrate with a high specific surface area.Its research and applications have expanded from traditional building materials to functional fields such as environmental remediation,owing to its unique crystal structure.This paper provides a comprehensive review of recent advances in TOB research and compares the differences between two common synthesis techniques(traditional hydrothermal and microwave-assisted hydrothermal methods).It further introduces various modification strategies,including ion doping,thermal activation,acid washing,and loading,which are employed to enhance the adsorption performance of TOB.The underlying mechanisms and current applications of TOB for removing nitrogen/phosphorus,heavy metals,and organic dyes from wastewater are also systematically summarized.Although TOB has demonstrated high adsorption potential,its large-scale applications still face a series of challenges.This paper aims to provide a theoretical foundation and technical reference for the functional development and sustainable utilization of TOB.Prospects for future research on TOB are also proposed,encompassing the development of efficient synthesis routes,optimization of modification techniques,and exploration of synergistic applications in multiple fields.
