Meanwhile, thermocatalytic reference experiment at 30 °C in the dark was carried out, the results were shown in Fig. 4c. It can be found from Fig. 4c that when the reaction sample kept at 30 °C in dark for 3 h, the degradation rate of MO is only 8.44%, which is much less than the degradation rate of 67.2% obtained under the exposure of NIR light at the same time.
