摘要
杂多酸是一类同时具有酸催化特性和氧化-还原能力的催化剂,有着广泛的应用前景。杂多酸固载化后,能够在液相氧化和酸催化反应中把催化剂从反应介质中很方便地分离出来,且能使这类均相催化反应多相化。本文介绍了以活性炭为载体的固载型杂多酸催化剂的研究状况,包括制备方法、影响负载量的因素及负载量对催化性能的影响,文章同时阐述了有关活性炭固载杂多酸的机理分析,总结了近年来活性炭固载杂多酸催化剂的应用研究及进展。
Heteropolyacid was a catalyst of both acid - catalytic properties and oxidation - reduction ability, with a broad application prospects. After immobilization of the heteropolyacid, the catalyst can conveniently isolated from the reaction medium in liquid -phase oxidation reactions or acid -catalyzed reactions, and also can make homogeneous catalyst heterogenize. The research of activated carbon supported heteropolyacid was introduced, including preparation methods, the factors affect loading content and effects of loading activated carbon supported heteropolyacid was expounded, and its summarized. content to catalytic performance. The mechanism of applied research and progress in the recent years were
