Summary:•Cesium lead halide perovskites are prepared by a facile solution-based technique.•Photocatalytic ability of the sample is explored by degradation of Eosin-B dye.•CsPbCl3 cubes showed maximum photocatalytic performance at visible light. All-inorganic cesium lead halide (CsPbX3, X = Cl, Br or I) perovskite cubes have been prepared by low-cost solution-based technique at room temperature. As synthesized perovskites were characterised by XRD, FESEM, TEM and FTIR. Photocatalytic activity of the as-synthesized cubes was investigated taking hazardous Eosin-B dye as model contaminant. Among all the synthesised samples, CsPbCl3 cubes showed superior catalytic performance and degraded the dye solution within 140 min under visible light. Going beyond well reported catalytic study on CsPbX3 quantum dots, this study not only establishes the potential of CsPbX3 cubes in dye degradation also provides new insight on the impact of morphology on it.
