A protocol producing the activated carbon (AC) with high surface area and porosity with large adsorption capacity from non-toxic and low cost precursor source was developed. The ACwas prepared from sugarcane bagasse with ZnCl2as activating agent. Three preparing temperatures including 400oC, 500oC, and 600oC were investigated to compare the structural difference of the ACs. The properties of the ACsfabricated at these temperatures were determined using relevant techniques such as scanning electron microscopy (SEM), X–ray diffraction (XRD), thermo–gravimetric analysis (TGA),Fourier transform infrared (FT–IR) spectroscopy and nitrogen adsorption/desorptionmeasurement.Characterization results showed that the maximum BET surface area of the AC is1502.1 m2/g at 500oC. XRD patternsand SEM micrographs revealed that the ACshave the amorphous structure and heterogeneous surface. IR spectra also proved the presence of functional groups O–H, O–N asymmetric and C–C aromatic in the carbon. Moreover, the maximum AC yield of 45.7% was achieved at 500oC.
