Modern industries rapid expansion has heightened energy needs and accelerated fossil fuel depletion, contributing to global warming. Additionally, organic pollutants present substantial risks aquatic ecosystems due their stability, insolubility, non-biodegradability. Scientists are currently researching high-performance materials address these issues. LaFeO3 nanosheets (LFO-NS) were synthesized in this study using a solvothermal method with polyvinylpyrrolidone (PVP) as soft template. The LFO-NS demonstrate superior performance, large surface area charge separation than that of nanoparticles (LFO-NP). performance is further upgraded by incorporating ZIF-67. Our results confirmed the ZIF-67/LFO-NS nanocomposite have performances pure LFO-NP integration ZIF-67 enhanced promote LFO-NSwhich was various characterization techniques including TEM, HRTEM, DRS, EDX, XRD, FS, XPS, FT-IR, BET, PL, RAMAN. 5ZIF-67/LFO-NS sample showed significant activities for CO2 conversion, malachite green degradation, antibiotics (cefazolin, oxacillin, vancomycin) degradation. Furthermore, stability tests our optimal very active stable. based on scavenger experiments photocatalytic degradation pathways, it been established H+ •O2− vital decomposition MG antibiotics. research work will open new gateways prepare MOFs-Perovskites nanocatalysts exceptional
