Preparation and Characterization of Activated Carbon from Coconut Shell - Doped TiO2 in Water Medium

The objective of the study was to prepare the activated carbon material doped TiO2-P25 (P25) in order to determine the interaction occured in the water medium. The method was to prepare the activated carbon from coconut shell which had been cleaned, pyrolyzed, sieved then followed by physical activation using a thermal process. Preparation of P25 was to form structures of anatase crystals in the furnace at temperature of 500 degrees C for 3 hours. Both materials were mixed using distilled water until sol-gel was formed. Results of characterization using SEM showed that there is interaction between the activated carbon and P25 inserted in the pores of the carbon, while SEM-EDX showed the composition of carbon, titanium and oxide are 46.9%; 27.5% and 25.6%, respectively. Data from XRD showed the formation of peaks from P25 anatase crystals and the carbon. It was supported by data of Flourier Transform Infra Red (FTIR) which showed the bonds of -OH; C-H; C=C; CO and the O-Ti-O.
