催化氧化降解木质素的研究进展

本文从所用催化剂、反应条件、反应机理等几个方面综述了木质素催化氧化降解方面的研究,着重介绍了以O_2和H_2O_2为氧化剂的金属为催化中心的氧化降解,例如,金属有机催化氧化、金属/溴化物催化氧化、金属配合物催化氧化、金属复合氧化体系和钛矿型复合氧化物催化氧化、金属/分子筛催化氧化和以自身为氧化剂的催化氧化等,以及无金属催化氧化降解、微波辅助氧化降解、光催化氧化降解和电化学氧化降解。

Advances in catalytic-Oxidation degradation of lignin

The studies on catalytic-oxidation degration of lignin in recent years are reviewed in this paper. Metal catalytic-oxidation(including the reaction carried out with O2 and H2O2 as the oxidants such as: organometal catalytic-oxidation, metal/bromide catalytic-oxidation, metal complexe catalytic-oxidation, multiple-metal oxidants and Perovskite-type Oxide catalytic-oxidation, metal/zeolites catalytic-oxidation and catalytic-oxidation by the oxidants themselves), metal-free catalytic-oxidation, microwave assisted oxidative, photocatalystic oxidization, electrochemical oxidation for upgrading lignin and lignin model compounds are introduced emphatically. In this paper, the progress of catalytic-oxidation degration of lignin is reviewed according to the different catalyzers, reaction condition and mechanism.
