Pore-encapsulated catalysts for selective hydrogenolysis of plastic
Summary:
ISURF #05082 describes a catalyst and method to break down and recycle plastic, particularly polyethylene. The catalyst mimics enzymes in that it first seeks to template the polymer chain in a configuration that yields a narrow distribution of end products. Mesoporous silica nanoparticles (MSN) are used as scaffolds that polyethylene chains...
