摘要:

托贝莫来石(TOB)是一种具有高比表面积的层状硅酸钙水合物,因其独特的晶体结构,研究与应用已从传统建材领域拓展至环境修复等功能领域。本文系统梳理了TOB国内外的最新研究成果,对比了传统水热法与微波水热法两种常用合成技术的差异,介绍了为提升其吸附性能采用的不同改性方式(如离子掺杂、热活化、酸洗、负载等),并总结了其对废水中氮磷、重金属和染料等污染物的吸附机理及应用现状。尽管TOB已表现出高效的吸附潜能,但其规模化应用仍面临一系列挑战。本文旨在为TOB的功能化拓展与可持续应用提供理论依据和技术参考,并对未来研究方向提出展望,包括开发高效制备工艺、优化改性技术及探索多领域协同应用等。

Abstract:

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.
