Ti3C2-MXene material, known for its strong electronic conductivity and optical properties, has emerged as a promising alternative to noble metals cocatalyst the development of efficient photocatalysts used in environmental cleanup. In this study, we investigated photodegradation crystal-violet (CV) dye when exposed UV light using newly developed photocatalyst Ti3C2-MXene/NiO nanocomposite-decorated CsPbI3 perovskite, which was synthesized through hydrothermal method. Our research investigation into structural, morphological, characteristics Ti3C2-MXene/NiO/CsPbI3 composite techniques such FTIR, XRD, TEM, SEM–EDS mapping, XPS, UV–Vis, PL spectroscopy. The photocatalytic efficacy assessed by evaluating ability degrade CV an aqueous solution under UV-light irradiation. Remarkably, displayed significant improvement both degradation rate stability compared nanocomposite perovskite materials. Furthermore, UV–visible absorption spectrum demonstrated reduced band gap 2.41 eV, is lower than that (3.10 eV) (1.60 eV). practical terms, achieved impressive 92.8% within 90 min exposure. We also confirmed role photogenerated holes radicals removal process radical scavenger trapping experiments. Based on our findings, proposed plausible mechanism composite. This may open up new avenues cost-effective high-performance MXene-based photocatalysts, utilizing abundant sustainable materials remediation.
