In this research work, a simple soft chemical synthesis route is adopted to synthesize (Sn1-xMnxO2-δ; where x=0, 0.05, 0.10, 0.15 and 0.20) based ceramic nanoparticles. The prepared nanoparticles were characterized to X-ray diffraction (XRD), FTIR spectroscopy, particle size analysis, SEM, EDAX, UV and photoluminescence (PL) studies. From XRD, the crystalline geometry of ceramic nanoparticles was found to be tetragonal. FTIR data have shown a broad absorption band at a wavelength of ~ 600 cm-1 due to M-O stretching vibration mode. The ceramic nanoparticles were found to be in the range of 704 to 1258 nm. Smaller grains Sn0.95Mn0.05o2-δ exhibited better photocatalytic degradation behavior (84.8%) under visible light after 120 minutes of irradiation.

In this research work, a simple soft chemical synthesis route is adopted to synthesize (Sn1-xMnxO2-δ; where x=0, 0.05, 0.10, 0.15 and 0.20) based ceramic nanoparticles. The prepared nanoparticles were characterized to X-ray diffraction (XRD), FTIR spectroscopy, particle size analysis, SEM, EDAX, UV and photoluminescence (PL) studies. From XRD, the crystalline geometry of ceramic nanoparticles was found to be tetragonal. FTIR data have shown a broad absorption band at a wavelength of ~ 600 cm-1 due to M-O stretching vibration mode. The ceramic nanoparticles were found to be in the range of 704 to 1258 nm. Smaller grains Sn0.95Mn0.05o2-δ exhibited better photocatalytic degradation behavior (84.8%) under visible light after 120 minutes of irradiation.
