In this research paper, visible light-driven ABO3 type (perovskite) lanthanum chromite (LaCrO3; labeled as LCO) and Co-Ni co-doped lanthanum chromite (La1-xCoxCr1-yNiyO3 (x,y = 0.50); labeled as LCCNO) photocatalyst were synthesized by following a facile microemulsion technique. Later, to fabricate their reduced GO-based (La1-xCoxCr1-yNiyO3/r-GO; labeled as LCCNO/r-GO) nanocomposite: LCCNO nanoparticles were decorated on reduced graphene oxide (r-GO) using ultrasonication method to achieve high degradation of carcinogenic and toxic pollutants from the environment. The as-fabricated nanoparticles (NPs) were subjected to different advanced instrumentations regarding their structural and application analysis. The structural, morphological, specific surface area and elemental analysis were studied by XRD (x-ray diffraction), FT-IR (Fourier Transform-Infrared Spectroscopy), SEM (Scanning Electron Microscopy), BET (Brunauer Emmett Teller) and EDX (Energy Dispersive X-ray), respectively. The optical analysis and current-voltage (I-V) experiment was employed to investigate the impact of Co-Ni ions co-doping and r-GO on the bandgap and conductivity of the fabricated material, respectively. Regarding their environmental application study, the fabricated nanomaterial's photocatalytic activity (PCA) was tested against the photodegradation of crystal violet (CV) dye. LCCNO/r-GO NCs photocatalyst showed maximum CV dye photodegradation efficiency (99.02%; 100 min) as compared to pure LCO (36.44%; 100 min) and co-doped LCCNO (73.74%; 100 min) photocatalysts due to its lower band gap (2.14 eV), higher conductivity (6.4 × 105 Sm-1) and larger surface area (123.7 m2/g). According to PCA study, a dose of 20 mg of LCCNO/r-GO photocatalyst degrades cationic CV dye effectively in basic media (pH–11). Furthermore, scavenging tests were employed to investigate the generation of radical species (.O2 and OH∙) during (PCA) experiments. The structure constancy and reusability of the LCCNO/r-GO photocatalyst was observed for five cycles. It lost 5.71% degradation efficiency against CV dye after five cyclic tests. This research provides new insight into developing high-quality structured photocatalysts for environmental remediation under sunlight irradiations.

A novel TiO2/g‐C3N4/CuFe2O4 nanocomposite is synthesized via a wet impregnation process and has been evaluated for photocatalytic degradation of organic pollutants such as Amoxicillin (Antibiotic), Chlorpyrifos (Pesticide), and Methylene blue (Dye) under dark and visible light conditions in water. The synthesis and its photocatalytic characterization of nanocomposite are analyzed using XRD, FT‐IR, HR‐SEM, TEM, EDS, XPS, UV‐Vis, DRS, PL, BET, EIS, VSM, and ESR analysis. Among the various organic pollutants analyzed using TiO2/g‐C3N4/CuFe2O4 to serve as a photocatalyst, the degradation of MB pollutant was significantly greater (99.5 %, k=0.0533 min−1) in comparison to the degradation of the AMX (97.6 %, k=0.0346 min−1) and CPF (97.3 %, k=0.0340 min−1) during visible light irradiation for a period of 90 minutes. The recyclability is validated over three cycles, displayed its stability with 76 % degradation of pollutants and the photocatalyst is also easily separated using a simple magnet for further recycling study. As observed in the results of ESR, the formation of O2 significantly accelerated the superoxide radical generation during the photocatalytic degradation of pollutants, enhancing degradation efficiency. It is worth highlighting that the remarkable degradation efficacy, stability and reusability exhibited by the synthesised nanocomposite prove advantageous for subsequent applications.
