Fig. 8. (A) Conversion rate of 4-nitrophenol as a function of time after the addition of NaBH4: (a) TG0.5A0.5, (b) TA0.5G0.5, and (c) control test without a catalyst. (B) Conversion rate of 4-nitrophenol after reaction for 18 min using our samples with different dosages of GO sheets: (a) TGxA0.5 and (b) TA0.5Gx (x = 0, 0.1, 0.5, and 1.0 wt%).
