dc.description.abstractThe low conductivity and high combination rate of photogenerated electrons (e-) and photogenerated holes (h+) are the real challenges of photocatalysis. These problems could be mitigated by the synthesis of heterostructured nanocomposites (NCs). In this study, Bi@CNT-Fe2O3 nanocomposite was fabricated via pulsed laser ablation in liquid and characterized by UV-Vis spectroscopy, photoluminescence (PL), X-ray diffraction (PXRD) and field scanning electron microscopy (FESEM). These techniques revealed successfully the formation of CNT-alpha-Fe2O3 and Bi@CNT-alpha-Fe2O3 nanocomposites. The photocatalytic activities of the Fe2O3, CNT-alpha-Fe2O3, and Bi@CNT-Fe2O3 photocatalysts were evaluated by the degradation of methylene blue (MB) dye under ultraviolet (UV) light irradiation in the presence of a very low concentration of hydrogen peroxide (H2O2) as an oxidizing agent. The results show that the Bi@CNT-alpha-Fe2O3 NC has the highest photocatalytic degradation efficiency of MB which completes in 20 min of UV light irradiation. In addition, the obtained rate constants (min-1) of Bi@CNT-alpha-Fe2O3 NC were 1.3 and 3.4 times higher than those of CNT-alpha-Fe(2)O(3 )and alpha-Fe2O3. nanocatalysts, respectively.en_US
