عنوان انگلیسی Enhanced Photocatalytic Degradation of CaTiO3 and Sm@CaTiO3 Nanoparticles for Wastewater Treatment and Solar Cell Applications
چکیده انگلیسی مقاله A one-step green synthesis approach has been used successfully to synthesize undoped and Sm-doped calcium titanate nanoparticles (NPs). In particular, we prepared undoped and Sm-doped CaTiO3 NPs using Tridax procumbens leaf extract as the catalyst for the first time. From XRD analysis, the calculated crystallite size is 23.92 nm and 24.32 nm, respectively, for undoped and Sm-doped CaTiO3 samples. From the UV-Vis analysis, the calculated band gap is 3. 59 eV and 3.56 eV respectively for the undoped CaTiO3 and Sm-doped CaTiO3 nanoparticles. Owing to their distinctive morphologies, flower-like CaTiO3 NPs possess a high level of photocatalytic activity when exposed to UV light. As a result of varying degradation times, the synthesized material was used to photodegrade methylene blue dye. Under UV light irradiation, undoped and Sm@CaTiO3 exhibited effective photocatalytic properties, which may explain the existence of active oxygen and hydroxyl radicals. During the cyclic activity, CaTiO3 doped with Sm did not exhibit any changes in phase or structure, proving that it is highly stable during degradation.
