Figure 4.
UV–vis absorption spectra of degradation of 0.02 mM (a) RhB; (b) MB; and (c) MR by NaBH4 (0.4 M) in the presence of 0.2 mg of Pd/g-C3N4 as the nanocatalyst. (Inset) Absorbance vs time plot and (d) plot of ln(Ct/C0) vs reaction time representing first-order kinetics for the degradation of organic dyes.
