Fig. 9From: Enhanced Photocatalytic Performance of Luminescent g-C3N4 Photocatalyst in Darkroom a Decomposition of MB by the repeated reactions in the dark by adding various samples irradiated by an 8-W black lamp for 30 min. Each photocatalytic reaction time was 10 h and 10 times of reactions were conducted. b Degradation rate of MB after 150 h irradiation (10 times of repeated reactions)Back to article page
