UV-vis spectra of MO (a) and MB (b) reduction as a function of time by NaBH4 in the presence of Fe/CC-CH catalytic strip, Percent C/C0 vs time for Rh-B, MO and MB (c), and and their Ln(C/C0) values as a function of time (d) Experimental conditions: 3 mL of 0.05 mM Rh-B or MO or MB solution with 0.5 mL of 0.1 M NaBH4 aqueous solution and 0.4 × 2 cm2 of the respective catalytic strip.
