Making Polypyrrole/Graphene Oxide Composite Nanosheets and Using Them to Remove Cr (VI) From Aqueous Solutions

Using the sacrificial-template polymerization approach, we describe the straightforward, dependable synthesis of polypyrrole (PPy)/graphene oxide (GO) composite nanosheets in this study. Here, PPy, which acted as both the oxidant and the sacrificial template, was deposited onto MnO2 nanoslices. MnO2 was continuously consumed during the polymerization of pyrrole on the surface of GO nanosheets. As a result, the PPy that is developing on the surface of GO nanosheets resembles MnO2 nanoslices in shape [1]. Due to its independence from removing the template, which is typically a difficult and time-consuming experimental operation, this method can allow the manufacture of PPy nanostructures more readily than the standard route. Based on the synergy effect, the asprepared PPy/GO composite nanosheets showed improved characteristics for removing Cr(VI) ions in aqueous solution. The PPy/GO composite nanosheets have an adsorption capacity that is roughly twice as great as that of regular PPy nanoparticles. We think that our research may provide a fresh, efficient route for enhancing adsorption's capacity to remove heavy metal ions from waste water [2].
