金属-有机框架材料在石化环保领域的应用

Environmental applications of metal-organic frameworks in petrochemical industries

石油化工是我国的支柱产业,也是环境污染的主要来源。近年来,随着国家环保形势的日益严峻和相应环保法规的陆续出台,高效处理石化行业所涉及的各类污染问题已成为重中之重。作为一种新型的纳米多孔材料,金属-有机框架(MOF)在石化环保领域展现出了广阔的应用前景。该材料可作为高性能吸附剂、分离膜以及催化材料去除或降解石化行业中的典型污染物。本文系统梳理了MOF材料及其相关工艺在石化环保领域的潜在应用,重点介绍了近年来国内外取得的突破性进展,并在此基础上深入分析了该材料的应用现状、存在问题及未来的研发方向。总体而言,MOF材料具有比传统多孔材料更优异的结构特征和应用性能;展望未来,其能够作为吸附剂、分离膜或是催化材料在石化环保领域得到更大规模的推广与应用。

Petrochemical industry is one of the core industries in China,whilst it is also a main source of environmental pollutions.Since the nation's environmental situations become severer together with the fact that more and more environmental regulations have been installed,the effective remediation towards the typical petrochemical-related contaminations is now a priority topic.As a recently-developed class of material,metal-organic frameworks(MOF)have exhibited promising application potentials for environmental remediation in petrochemical industries.The materials could work as effective adsorbents,functional membranes as well as catalytic candidates to remove/separate/degrade petrochemical pollutants.This article reviews the relevant applications in this field,analyzes the most significant work,and finally discusses the future perspectives for the further development of MOF materials.Overall,MOF materials have exhibited better structural features and application performance.It shall work favorably as adsorbents,membranes and catalysts in the environmental areas of petrochemical industries in the future.
