1. A method for depolymerizing lignin, the method comprising reacting lignin-containing material 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, to produce depolymerized products from said lignin.
