Abstract
Official abstract text for this publication.
A hierarchical catalyst composition comprising a continuous or particulate macroporous scaffold in which is incorporated mesoporous aggregates of magnetic nanoparticles, wherein an enzyme is embedded in mesopores of the mesoporous aggregates of magnetic nanoparticles. Methods for synthesizing the hierarchical catalyst composition are also described. Also described are processes that use the recoverable hierarchical catalyst composition for depolymerizing lignin, remediation of water contaminated with aromatic substances, polymerizing monomers by a free-radical mechanism, epoxidation of alkenes, halogenation of phenols, inhibiting growth and function of microorganisms in a solution, and carbon dioxide conversion to methanol. Further described are methods for increasing the space time yield and/or total turnover number of a liquid-phase chemical reaction that includes magnetic particles to facilitate the chemical reaction, the method comprising subjecting the chemical reaction to a plurality of magnetic fields of selected magnetic strength, relative position in the chemical reaction, and relative motion.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for inhibiting growth of microorganisms in a solution, the method comprising contacting said solution with a hierarchical catalyst composition comprising a continuous macroporous scaffold in which is incorporated self-assembled mesoporous aggregates of magnetic nanoparticles containing a free-radical-producing enzyme embedded in mesopores of said mesoporous aggregates of magnetic nanoparticles; contacting said mesoporous aggregates to hydrogen peroxide; wherein said free-radical-producing enzyme produces free-radicals from said hydrogen peroxide that diffuse from said mesoporous aggregates; and inhibiting the growth of said microorganisms with said free-radicals. 2. The method of claim 1 , wherein said free-radical-producing enzyme comprises a lactoperoxidase. 3. The method of claim 2 , wherein said lactoperoxidase is combined with a glucose oxidase.
