Photocatalytic dye degradation experiments were conducted using a Xenon lamp with a power output and light intensity of 485 mW/cm², equipped with a UV cut-off filter. A solvent mixture of 25 mL consisting of 10% (v/v) ethanol in toluene was used for all experiments. The concentrations of the catalyst and dye were maintained at 400 mg/L and 16 mg/L, respectively, across all trials to ensure consistency. Prior to degradation, the catalyst and dye were dispersed via sonication for 5 minutes to ensure homogeneity. All measurements were performed at ambient temperature under continuous stirring to maintain uniform reaction conditions. To address the high pH dependency, we stirred the BCG solution in the dark for 30 minutes following the addition of the catalyst to allow pH stabilization.. The micrograph of the CPB/ZIF-8 nanocomposite reveal the distribution of CPB particles across the ZIF-8 surface (Figure ). Further TEM analysis (Figure ) confirms this result,
