In this study, an efficient photocatalyst for dissociation of water was prepared and studied. The chromium oxide (Cr₂O₃) with Titanium dioxide (TiO₂) nanofibers (Cr₂O₃-TNFs) nanocomposite with (chitosan extract) were synthesized using ecologically friendly methods such as ultrasonic and hydrothermal techniques; such TiO₂ exhibits nanofibers (TNFs) shape structure. Doping TiO₂ with chromium (Cr) enhances its ability to absorb ultraviolet light while also speeding up the recombination of photogenerated electrons and holes. The prepared TNFs and Cr₂O₃-TNFs were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDX), and UV-Visible absorbance. The XRD of TNFs showed a tetragonal phase with 6.9 nm of average crystallite size, whereas Cr₂O₃-TNFs crystallite size was 12.3 nm. FE-SEM images showed that the average particle size of TNFs was in the range of (9-35) nm and UV-Vis absorbance of TNFs showed their energy gap to be 3.9eV while the energy gaps of Cr₂O₃-TNFs were smaller equal to 2.4 eV. The highest hydrogen production rate for the Cr₂O₃-TNFs nanocomposite was 4.1ml after 80min of UV exposure. Cr₂O₃-TNFs have high photocatalytic effectiveness due to their wide ultraviolet light photoresponse range and excellent separation of photogenerated electrons and holes.
