In the present studies, cytotoxicity evaluation of camphor-mediated bimetallic nanoparticles has been done. The IC50 value of Te combined Se, Zr, and Ce bimetallic nanoparticles are 18.0, 16.0, 175.4,38.9 µg/ml respectively. A maximum proportion of cell activity attained at 16 µg/ml reveals the size-dependent anticancer property of TeSe, Tezr, and TeCe BNPs towards the MCF -7 Cell line and SeZr towards skin cancer cell lines. The surface morphology with particle size and optical attribute of camphor-mediated BNPs can be analyzed by various studies such as Uv- visible spectroscopy, XRD, AFM, SEM –EDX, HR-TEM, and XPS study the size of the SeZr BNPs was observed to less than 100 nm, which conforms to the bioactive nature of bimetallic nanoparticles. In addition, the photocatalytic behaviour of camphor-mediated SeZr BNPs has been tested by using methylene blue dye under natural sunlight and UV illumination. Hence, the result of the studies shows a maximum of 87% degradation within 60 min for same concentration solution at PH 9 which can be due to increases in hydroxyl ion concentration. Further, a comparative study in catalytic activity on photo degradation of MB dye with an optimized sample was carried out under UV irradiation. The reusability test was performed after 60 min degradation, implying the Photocatalyst’s stability. Further, pseudo -first- order kinetic model was performed for obtained data. This is the first report on catalytic degradation using camphor-mediated SeZr BNPs to effective removal of pollutants in waste water streams
