Scanning electron microscopy with energy dispersive X-ray
spectroscopy (SEM-EDS) was used to obtain information about the
morphology and size of the samples. The morphology study of the
catalystswas carried out using a JEOL scanning electron microscope
model JSM-6400 while elemental chemical analysis done with the
EDS technique. Furthermore, bulk metal content present in the
catalysts was determined by using Inductive coupled plasma-
Atomic emission spectrometer (ICP-AES), PerkinElmer Emission
Spectrometer Model Plasma 1000.
