Seeking environmentally friendly halide perovskite photocatalysts: synthesis, structure and photocatalytic performance exploration

Halide perovskites have high photoelectric conversion efficiency, making them promising candidates for photocatalysis. However, their toxic and unstable nature limits their applications. Here, we successfully synthesised three hybrid Bi-based halide perovskites: (HTMG) 3 Bi 2 Br 9 ( 1 ), (HEI) 2 BiB...

Summary:Halide perovskites have high photoelectric conversion efficiency, making them promising candidates for photocatalysis. However, their toxic and unstable nature limits their applications. Here, we successfully synthesised three hybrid Bi-based halide perovskites: (HTMG) 3 Bi 2 Br 9 ( 1 ), (HEI) 2 BiBr 5 ( 2 ) and (HTMA) 3 Bi 2 Br 9 ( 3 ). X-ray single-crystal diffraction analysis shows that they all contained 0D structures composed of isolated Bi-Br clusters. The three compounds showed excellent degradability and cycling stability for Sudan III dissolved in ethanol under simulated sunlight. In addition, the photocatalytic degradation performance of four Bi-based halide perovskites previously reported by our group is also characterised and summarised in this work. Three cases of hybrid bismuth-based halide perovskites were synthesized and used for photocatalytic degradation of Sudan III under simulated sunlight.
