催化氧化工艺是实现挥发性有机化合物(volatile organic compounds,简称VOCs)趋零排放的关键技术,而催化剂载体发挥着重要作用。本文综述了近些年来国内外科研工作者在VOCs催化氧化催化剂载体方面的创新性工作,包括金属氧化物载体、柱撑黏土载体(pillared interlayer clays,简称PILCs)、三维有序大孔材料(three-dimensionally ordered macroporous material,简称3DOM)载体、分子筛等载体用于VOCs催化氧化反应,并分析了载体结构特征、孔道结构、表面物理化学性质及活性组分的分散作用等对催化反应效果的影响,从而为高性能催化氧化催化剂载体的设计、研发及优化提供建议。
Catalytic oxidation is a key technology to achieve zero-emission of volatile organic compounds (VOCs), and catalyst supports play an important role. This review summarizes the recent innovations of scientists at home and abroad on VOCs catalysts for catalytic oxidation of catalysts, including metal oxide supports, pillared interlayer clays (PILCs), and three-dimensional ordered macroporous materials -dimensionally ordered macroporous material (3DOM) carrier and molecular sieve for the catalytic oxidation of VOCs. The effects of the structure, pore structure, physical and chemical properties of the support and the dispersion of the active components on the catalytic reaction were analyzed. Thus providing suggestions for the design, development and optimization of high performance catalytic oxidation catalyst carrier.
