Zeolite-Y templated carbon (ZTC) has been activated with K 2 CO 3 and ZnCl 2 . This research aims to compare the characteristics of ZTC with K 2 CO 3 and ZnCl 2 activation. ZTC was synthesized via impregnation method followed by carbonization. In this research, activation process was conducted at variation of activator/carbon weight ratio of 1 and 1.50. The activation was carried out by heating up impregnated carbon at 800 °C for 1 h followed by washing to remove inorganic salt. XRD and SEM results indicate that the use of different activator produce ZTC with varied structure and morphology. Diffractogram results showed that the graphitic peak decreased due to K 2 CO 3 activation, whereas graphitic peak increased owing to ZnCl 2 activation. Decreasing the graphitic peak indicates that ZTCs have higher pore structure formation. In addition, surface formation of ZTC activated by K 2 CO 3 was higher than by ZnCl 2 activation. The higher pore structure formation means the amount of carbon deposited on external surface material was decreased.
