Mesoporous catalysts of magnetic nanoparticles and free-radical producing enzymes, and methods of use

A composition comprising mesoporous aggregates of magnetic nanoparticles and free-radical producing enzyme (i.e., enzyme-bound mesoporous aggregates), wherein the mesoporous aggregates of magnetic nanoparticles have mesopores in which the free-radical-producing enzyme is embedded. Methods for synthesizing the enzyme-bound mesoporous aggregates are also described. Processes that use said enzyme-bound mesoporous aggregates for depolymerizing lignin, removing aromatic contaminants from water, and polymerizing monomers polymerizable by a free-radical reaction are also described. 种包括磁性纳米粒子的介孔聚集物和产生自由基的酶(即，结合酶的介孔聚集物)的组合物，其中所述磁性纳米粒子的介孔聚集物具有介孔，在所述介孔中嵌入所述产生自由基的酶。本申请还描述了用于合成结合酶的介孔聚集物的方法。本申请还描述了使用所述结合酶的介孔聚集物将木质素解聚、从水中消除芳香族污染物、以及通过自由基反应使可聚合的单体聚合的工艺。
