Physicochemical and magnetic properties of samarium doped titanium dioxide nanoparticle synthesized by hydrothermal methods with various sintering time

TiO2 has a variety of uses, including gas sensors, catalytic performance, and as a reasonably priced and environmentally friendly photocatalyst. By synthesizing titanium dioxide nanoparticles with samarium and different sintering times, this work seeks to boost the effectiveness of these particles. A solvothermal technique was used to create nanoparticles of TiO2 that were doped with samarium. X-ray diffraction, fourier transform infrared (FTIR), vibrating sample magnetometer, scanning electron microscopy (SEM), and (VSM). First, 10 ml of ethanol and 0.1 ml of distilled water were used to dissolve 58 mol of samarium (III) acetate hydrate. The mixture then received 1 ml of titanium diokside that had been dissolved in 10 ml of ethanol. For three hours at room temperature, the solution was agitated with a magnetic stirrer. After stirring, the solution was transferred to a 20 ml stainless steel autoclave that had been lined with teflon and heated to 120 °C for 5 hours. The solution was also three times cleaned with ethanol after being allowed to cool at room temperature. The resulting white precipitate was gathered and allowed to dry for 12 hours at 60 °C. The dry sample underwent sintered for 1 or 2 hours at 500 °C. The XRD results demonstrated that the addition of sintering time decreased the crystallinity of Ti(Sm)O2. The SEM analysis revealed that the Ti(Sm)O2 sample had nice spherically shaped particles. The FTIR results revealed that the Ti-O bending mode of vibration has characteristics of 844 cm-1 and 815 cm-1 at various sintering times of 1 and 2 h. The sample’s paramagnetic characteristics were shown by the VSM result.
