| Summary: | Microwave-assisted Palladium/Reduced Graphene Oxide (Pd/RGO) synthesis
was effectively carried out in this study, which looked at the effects of different Pd loading
weights in Graphene Oxide (GO) on its physicochemical qualities. The Tour technique
was used to make GO, with a KMnO4:graphite weight ratio of 3.5. Meanwhile, Pd/RGO
was synthesized utilizing the in-situ reduction method of one-pot synthesis with ascorbic
acid as the green reducing agent, yielding Pd-0.5/RGO, Pd-1.0/RGO, and Pd-2.0/RGO,
respectively, with variations in Pd loading weight of 0.5, 1.0, and 2.0%. XRD, FTIR, SAA,
SEM-EDX, and TEM were used to examine all material characterizations. As a result,
Pd-1.0/RGO had the largest surface area of 65.168 m2/g among the Pd-based materials,
with a pore volume of 0.111 cc/g, the pore diameter of 3.316 nm, Pd crystallite size of
28.29 nm, RGO nanostructure dimension of 3.37 × 28.53 nm, and reduction level (C/O)
of 3.02. This material also contains specific functional groups, including O-H, C-H, CO2,
C=C, C=O, and C-O, based on FTIR spectra. Therefore, optimal weight loading of metal
on the surface of the supporting material will provide a large material surface area.
Increasing the surface area of the material improves its performance as a catalyst.
