Photocatalytic H2O2 production performance and corresponding evolution rates with different MA-KI ratio samples (before and after photocatalytic oxidation) (a, b), and CN, CN-KI, CN-KI3-KI, and CN-KI3-KI-MV samples (c,d). The error bars represent the standard deviation of three replicate tests. e Schematic diagram of dynamic photoproduction of H2O2 in the CN-KI3-KI-MV system. Inset: accumulated amount of H2O2. f Long-term photocatalytic H2O2 production activity of CN-KI3-KI-MV and photocatalytic H2O2 production activity in HPLC wastewater. Inset: The corresponding detection of H2O2 color change. Photocatalytic degradation activity (g) and antibacterial properties (h) of CN, CN-KI, CN-KI3-KI, and CN-KI3-KI-MV. i Scenario diagram of the applications for the CN-KI3-KI-MV system. j Comparison with other recently reported photocatalysts for H2O2 production.
