Abstract
Polypyrrole/graphene oxide (PPy/GO) was synthesised and evaluated as an effective photocatalyst to degrade 2-chlorophenol from aqueous solution under solar light irradiation. The PPy/GO composite was synthesised by the incorporation of PPy with GO using Hummer's method(s). Three different compositions of PPy/GO composites were prepared with a varying ratio of PPy and GO (1:1, 1:4, and 9:1). The physicochemical properties of PPy, GO, and the synthesised PPy/GO composites were characterised using FTIR, UV-Vis, XRD, and SEM with EDX. The results revealed that PPy was successfully integrated with GO forming PPy/GO composites. The photodegradation of 10 ppm of 2-chlorophenol has been observed under sunlight for 3 hours with the exposure contact time of 180 minutes before being tested with UV-Vis in order to obtain the percentage of degradation in the sunlight. The degradation study demonstrates that PPy/GO composite with the ratio of 1:1 exhibited the highest percentage of degradation with - 71.08 % at 180 minutes and 68.96 % at 3 hours.
