Rapid Degradation of Unmanageable Polycyclic Aromatic Hydrocarbons by C-ZnO Solid Solution Nanocatalyst

Abstract

C atom doped ZnO solid solution (C-ZnO SS) nanocatalyst with excellent photocatalytic activity was successfully synthesized by one-step combustion method. The deposition of C dots on surface and the doping of C atom in the ZnO crystal were reliazed simultaneously. The “sucker effect” between C dots and C-ZnO SS in the nanocatalyst was found. Therein, the big specific surface area, the increased crystal defect and the enhanced separation of photo-generated carriers brought to high degradation rate for naphthalene and anthracene. The complete degradation time of unmanageable polycyclic aromatic hydrocarbons was only several hours by C-ZnO SS as nanocatalyst. In addition, a positively correlated conclusion about the degradation rate and the electron density of benzene rings was proposed. This research provides a new nanocatalyst for degrading unmanageable pollutants in the environment.
