Graphical Abstract
  • -functionalized nickel/silver/graphene quantum dot/graphene hybrid for the colorimetric detection of malathion [28]. This paper describes the development of an electrochemical sensor based on a graphene quantum dot-modified glassy carbon electrode (GQDs/GCE) for the determination and quantification of the
  • and 320 nm, in agreement with the data previously reported [30][31]. The shoulder at 270 nm is probably caused by π–π* transition of the C=C bonds, and the absorption hump at 320 nm is likely caused by n–π* transitions of the C=O bonds. As shown in Figure 2b, when the graphene quantum dot suspension

Graphical Abstract
  • introducing defects in metal oxide semiconductors opens up the possibility of their use in the visible spectrum [77]. Recently, Xie et al. reported using SnO2/graphene quantum dot (GQD) composites. They showed that the absorption edge of as-prepared SnO2 (Figure 13a black line) is around 340 nm, equaling to a
