In the present study, the synthesis of CFN‐800 photocatalyst (CdFe2O4, nanoparticles calcinated at 800 °C) has been achieved using ACM (auto‐combustion method). The confirmation of the formation of the CFN‐800 photocatalyst was done by using different characterization techniques such as FT‐IR, UV‐Vis, XRD, and SEM. Further, under environmental application, synthesized nanoparticles were utilized for the green photocatalytic degradation of industrial effluent Brilliant Blue FCF (BBF) in aqueous media using sunlight as a natural source of light. The degradation experiment was examined by using a UV‐vis spectrophotometer. Various parameters such as the amount of CFN‐800 photocatalyst (g), the concentration of dye (ppm), the amount of dye (ml), and the pH level (1–11) were analyzed to find the more efficient results in terms of % degradation of BBF dye solution. By experiments, the results found were that the photodegradation of BBF touched to 93 % in 100 min. with 0.010 g of CFN‐800 photocatalyst and 10 ppm dye solution (10 ml) at 5 pH. In addition, the prepared CFN‐800 photocatalyst showed excellent performance in recyclability. Even after recycling for up to four consecutive cycles, no significant decrease in the degrading efficiency of CFN‐800 was observed. CFN‐800 photocatalyst having a low band gap, small crystalline size with high crystallinity efficiently degraded the Brilliant Blue dye. CFN‐800 photocatalyst was more beneficial in terms of the small quantity of catalyst needed for dye degradation. It was also found to perform better in terms of low degradation time, deterioration in aqueous media, and solar light utilization as a green energy source.
