| Abstract: | Solar-driven photocatalytic H2O2 production is a sustainable and clean technique with respect to the traditional route. Here, the efficient H2O2 generation was accomplished by π?π coupling of AQ onto the few-layered graphitic carbon nitride (g-C3N4) nanoplates through one-step mechanochemical treatment. A H2O2 generation rate of 231 μM h?1 was obtained using AQ-coupled g-C3N4 nanoplates under visible light illumination, exceeding that of the g-C3N4 nanoplates and bulk g-C3N4 by 7-time and 14-time, respectively. Experimental results showed that the high oxygen reduction efficiency could be ascribed to the enhanced surface area, more exposed active sites and the distinct AQ roles of the electrons storage and restraining the charge recombination. This work inspired future work in synthesizing H2O2 through a sustainable and green route. |
