Herein, we introduce the first investigation into the photocatalytic properties of ultrathin Bi2O2S nanosheets prepared by a hydrothermal method. These nanosheets demonstrate exceptional efficiency in degrading congo red (CR) and rose bengal (RB) when exposed to visible light. The degradation rates reached approximately 82 % for CR and 80 % for RB, respectively. The rate constants for CR and RB degradation were found to be 1.8 × 10-2 min−1 and 1.3 × 10-2 min−1, respectively, during a 75 and 150-minute exposure to Bi2O2S nanosheets.
