提出了一种新的Ag@GQD（graphene quantum dot）杂化材料的制备方法：先用柠檬酸制备GQD，再用AgNO 3还原。催化研究表明，Ag@GQD杂化材料具有良好的光热效应和对4-硝基苯酚（4-NP）还原的催化性能，表明GQD通过协同效应提高了催化活性，Ag NPs通过SPR介导的光热局部加热提高了催化效率.
A novel Ag@GQD (graphene quantum dot) hybrid fabricated by a facile two-step strategy is presented: the GQDs are prepared by citrate acid and AgNO3 is reduced. Catalytic studies showed that the Ag@GQD hybrid exhibited excellent photothermal effect and catalytic performance for 4-nitrophenol (4-NP) reduction, suggesting that the GQDs enhanced the catalytic activity via a synergistic effect and the Ag NPs boosted the catalytic efficiency through SPR-mediated photothermal local heating.
