A simple biogenic route towards the Ag-decorated zinc oxide–carbon core–shell nanoparticles for visible light driven photodegradation |
초록 |
This work reports the novel biogenic synthesis of visible light active Ag-decorated zinc oxide–carbon (Ag-ZnO@C) core–shell nanoparticles for photocatalysis using an electrochemically active biofilm (EAB). ZnO@C core–shell nanoparticles were synthesized using a facile and single-step method, which involved the thermal degradation of a zinc aniline nitrate complex in methanol and further decorated with Ag using EAB as a biogenic reducing tool. The photocatalytic experiments showed that the Ag−ZnO@C nanocomposite possessed excellent visible light photocatalytic activity for the degradation of rhodamine B which was 250 and 125% higher than pure ZnO and ZnO@C. The enhanced photocatalytic activity was attributed to the delayed charge recombination due to the Ag- and nano-coating of carbon on ZnO along with the presence of oxygen vacancies. |
