Pyrochlore structure, Ce2Sn2O7 (CSO), with an ideal cubic structure, was successfully synthesised by two methods, the hydrothermal and microwave methods. Owing to their strong catalytic activity, oxygen defects, and unique size, pyrochlore-based oxides have attracted considerable attention in innumerable fields. Cerium stannate (Ce2Sn2O7) shows high efficiency in energy conversion and durability in performance, which makes it a promising candidate in the field of energy production. The crystal structure, morphology and sizes have been characterised by X-ray diffractometer (XRD), Raman spectrum, Scanning Electron Microscope (SEM), and Energy Dispersive Spectroscopy (EDS). The absorbance at 552 nm in the UV–Visible spectra of Ce2Sn2O7 (CSO) indicates the photocatalytic activity of the material and shows that the sample is optically active in the given configuration. The electrical measurements of the material over a range of temperatures show the effective ionic conductivity in the order of 10–7 S/cm. The results suggested that Ce2Sn2O7 has promising potential for electrochemical applications. The photocatalytic activity of the Ce2Sn2O7 solid solution was investigated under visible light irradiation in an ambient environment. The obtained Ce2Sn2O7 material possesses increased photocatalytic activity for the degradation of Rh B as well as various organic pollutants. These findings establish CSO as a high-performance, sturdy, and scalable photocatalyst, offering a promising resolution for pharmaceutical wastewater treatment and sustainable hydrogen production with minimal ecological risks.
