Porous carbon (PC) materials with high surface area can separate electronâhole pairs and adsorb organic pollutants more effectively. A series of nanocomposites were prepared by anchoring black TiO2 nanoparticles (BTN) onto PC through a calcination process. Chemical and structural features of samples were examined by Xâray photoelectron spectroscopy (XPS), Raman spectroscopy, powder Xâray diffraction (PâXRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analyses. The resulting adsorptionâphotocatalysis synergistic effect led to a dramatically improved photocurrent for BTN@PCs, thus indicating the high photocatalytic performance toward waterâsoluble organic species. For instance, the degradation of tetracycline under visible light reached 90â%, which is higher than that for activated carbon doped onto BTN (57â%) without any additional agents. Moreover, the degradation of other antibiotics (such as oxytetracycline and ciprofloxacin) and methylene blue were also studied, thus showing that this system has the potential to be used for water treatment.
