Composite ZIF-8 with Cs3Bi2I9 to Enhance the Photodegradation Ability on Methylene Blue
The development of green, efficient, and reusable photocatalysts is important for pollution degradation. In recent years, Cs<sub>3</sub>Bi<sub>2</sub>I<sub>9</sub> has been shown to be an effective photocatalyst. However, the rapid recombination of electrons and holes weakens the photocatalytic activity. In this work, the photogenerated electron transfer rate was promoted by ZIF-8 compositing with Cs<sub>3</sub>Bi<sub>2</sub>I<sub>9</sub>, which effectively improved the pollutant degradation. After 50 min of visible light irradiation, Cs<sub>3</sub>Bi<sub>2</sub>I<sub>9</sub>/ZIF-8 removed up to 98.2% of methylene blue (MB), which was 4.15 times higher than that of Cs<sub>3</sub>Bi<sub>2</sub>I<sub>9</sub> alone. In addition, the Cs<sub>3</sub>Bi<sub>2</sub>I<sub>9</sub>/ZIF-8 composite still exhibited high photocatalytic activity after three cycling experiments. Our research offers a simple and efficient method for enhancing the photocatalytic activity of lead-free halide perovskites.
