Fig. 2. UV-Vis absorbance spectra of (a) MB, (b) FLU, and (c) mixture of MeB and FLU dyes for the adsorption on ZnO@N-doped C at different times, where 5 mg of dye was dissolved in 100 mL and immersed with 10 mg of catalyst, (d and e) removal efficiencies of MeB and FLU using ZIF-8 and ZnO@N-doped C, and (f) adsorption of dyes using different amount of ZnO@N-doped C.
