W18O49/N-doped reduced graphene oxide hybrid architectures for full-spectrum photocatalytic degradation of organic contaminants in water†
Abstract
Full-spectrum photocatalysis from ultraviolet to near infrared has generated immense scientific interest in environmental purification and energy conversion, which is still a huge challenge. Herein, we utilized a solution combustion method to prepare W18O49/N-doped reduced graphene oxide (N-rGO) hybrid nanomaterials for full-spectrum photocatalytic degradation, which degraded organic dye molecules within a short reaction time (45 min) and demonstrated a high degradation rate (more than 90%) and a low initial concentration of degradation (50 mg Lā1). Moreover, the relationship between irradiation light source, temperature, time, photocatalytic properties and photocatalytic mechanism of the degraded organic dye molecules have been investigated. This research afforded a full-spectrum photocatalyst for effectively removing organic dyes under any wavelength range of sunlight, whether UV, Vis or NIR light.
