Abstrakt: The nanorods of all-inorganic lead-free perovskite cesium titanium bromide (CsTiBr3) are synthesized by solvothermal method for the first time. The thermogravimetric analysis reveals that there are no phase transition and crystallization processes for a temperature range of 25–700°C. The CsTiBr3 perovskite nanorods exhibit excellent photocatalytic degradation of congo red (CR) dye. The CR dye has complete degradation within 60 min under direct sunlight exposure using 5 mg of CsTiBr3 as a catalyst. The XRD analysis of the catalyst after photocatalytic degradation ensures the reusability of CsTiBr3.The complete removal of organic components of the dye is confirmed by COD analysis.
