Abstract
This study presents findings on the chemical synthesis of activated carbon from Saudi dates and its structural, chemical, and catalytic properties. Dates are among the top biowaste materials in the Kingdom of Saudi Arabia, and efforts are underway to utilize this resource. A chemical pyrolysis method was used to synthesize activated carbon from date stones. Synthesized activated carbon was calcined at different temperatures of 400, 500, 600, and 700 °C, and the impact of calcination temperature on the properties of activated carbon was investigated. For this purpose, contemporary characterization tools, namely, XRD, Raman spectroscopy, FTIR, SEM, TEM, TGA, DSC, and XPS, were employed. Results are discussed and compared with associated studies. Finally, the catalytic activity of gold-deposited activated carbon for the oxidation of cycloalkenes was evaluated, and it was found that the calcination temperature has a linear positive relationship with the catalytic activity.
Highlights
The synthesis of functional materials, such as catalysts, from biowaste is gaining importance due to increasing concern about the environmental impacts of major raw material consumption and due to the growing popularity of biowaste utilization
We investigated the synthesis of activated carbon from date stones in this study, and we explored the catalytic properties of the synthesized activated carbon
If the crystallite size increases with the rise in calcination temperature, we can expect a more packed structure with narrowing or temperature, a sharper peak is apparent in the X-ray diffraction (XRD) trends of activated carbon synthesized in this study
Summary
The synthesis of functional materials, such as catalysts, from biowaste is gaining importance due to increasing concern about the environmental impacts of major raw material consumption and due to the growing popularity of biowaste utilization. Researchers are finding ways to use a variety of biowaste materials, including palm shell, grape stalk, bamboo, coconut shell, olive mill, almond shell, walnut shell, durian shell, banana empty fruit bunch, corn cob, sugar cane, and rice husk, to make activated carbon [7]. This biowaste-synthesized activated carbon has been found to be useful in applications such as hydrometallurgy, catalysis, energy-storing materials, fuel cells, batteries, electrode materials, construction materials, pharmacy, and beyond [4,6,7,8]. Studies have investigated various procedures for synthesizing these materials and their effects
