Synthesis of Material Composite rGO-TIO2 From Coconut Shells by Sol-Gel Methods as Photocatalyst

The rGO- TiO₂ composite photocatalyst is receiving great attention because of its high performance. But the study of rGO- TiO₂ composite with sources of rGO material derived from the utilization of organic waste such as coconut shells is limited. In this study, the synthesis of nanocomposite rGO- TiO₂ was described with rGO obtained from coconut shells. The rGO samples produce through the oxidation and reduction process. The transformation of graphene oxide into reduced graphene oxide was assisted by microwave irradiation. The obtained rGO was then composite with Titanium tetraisopropoxide (TTIP) by the sol-gel method. The composite of rGO- TiO₂ was characterized by XRD, FTIR, UV-Vis, and SEM. The photocatalytic performance of the rGO- TiO₂ composite was conducted on Methylene blue. The result shows that rGO- TiO₂composite has a good photocatalytic performance with the highest number at 96%.
