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.
