Abstract
All inorganic lead-free halide double perovskite has great potential for high-efficient photocatalyst with the merit of low toxicity. Herein, double perovskite Cs2NaBiCl6 was designed as a photocatalyst for Malachite green degradation. Cs2NaBiCl6 was synthesized by a simple hydrochloric acid precipitation, and further employed to degrade organic dyes under ultraviolet light. The synthesized Cs2NaBiCl6 shows an excellent photocatalytic performance with a degradation efficiency of 99.7 % for malachite green (15 mg/L) in 25 min. Moreover, Cs2NaBiCl6 also exhibits good recyclability and stability. Further experiments confirm that superoxide radicals play a primary role in the photocatalytic degradation process. Our results prove that Cs2NaBiCl6 is a promising cost-effective and high-efficiency photocatalysts to degrade organic pollutants.
