Photocatalytic degradation of 2,4,4′-trichlorobiphenyl into long-chain alkanes using Ag nanoparticle decorated flower-like ZnO microspheres†
Abstract
Toxic 2,4,4′-trichlorobiphenyl (PCB28) was photocatalytically degraded by the action of Ag nanoparticle decorated nanosheet-assembled ZnO microspheres via a new photocatalytic degradation pathway. The outright degradation into long-chain alkanes via ring-opening reactions was demonstrated by gas chromatography-mass spectrometry.
