This negligible absorption was verified by the significant stability of the MO solution under the exposure of UV light for different periods, in the absence of a catalyst. MO was degraded up to 43% in the presence of TNFs, compared to 30% degradation by commercial TiO2-P25. While the degradation was remarkably accelerated to 96% for TNFG-2 within the measured time interval, rGO itself degraded MO by 20%.
