Producing Hydrogen Energy Using Cr2O3-TiO2 Nanocomposite with Animal (Chitosan) Extract via Photocatalaysis

In this study, an efficient photocatalyst for water splitting was developed. The Cr2O3 and TiO2 nanoparticles (Cr2O3-TNPs) nanocomposite with (Chitosan extract) created using ecologically friendly methods, such as the impregnation technique exhibits nano spherical (TNPs) shape structure. According to researchers, material enhanced its ability absorb ultraviolet light while also speeding up recombination of photogenerated electrons holes. TNPs prepared Cr2O3-TNPs were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy dispersive x-ray spectroscopy (EDX), UV-visible absorbance. XRD showed a Tetragonal phase 8.9 nm average crystallite size 14.2 nanocomposite. FE-SEM images that particle in range (12.5-57.5) UV-VIS absorbance has gap 3.8 eV, is 2.8 eV. It found performance photocatalysts hydrogen generation superior. gave highest rate production (3.6) ml at 80 min when exposed light. Moreover, revealed high H2 under ultraviolt irradiation (λ < 400 nm). Cr2O3-TNps have photocatalytic effectiveness due their wide photoresponse excellent separation
