• turn helps to foster the movement of photogenerated carriers. Furthermore, the high photocatalytic activity of the BiOI/Bi2O2CO3/RGO composite can be attributed to the fact that the positively charged BiOI/Bi2O2CO3 was electrostatically paired with the negatively charged graphite oxide (GO) to form

• , because it has only a few functional groups on its surface, which limits the chemisorption of gas molecules [28]. Graphene oxide (graphite oxide, GO), in contrast, has numerous oxygen functionalities and few remaining π bonds and is therefore electrically insulating [29]. GO can be reduced (reduced

• . However, the choice of graphite or g-C3N4 has shown little to no difference in the synthesis of nanoparticles. We have also studied exfoliation of graphite and graphite oxide (GO) under microwave irradiation in the presence of Zn metal. We have observed exfoliation of graphite into few-layered graphene
