Bismuth oxide/activated carbon composite was prepared from precursors of bismuth nitrate pentahydrate and activated carbon. At first, the Bi(NO 3 ) 3 solution was mixed with activated carbon. The activated carbon used varies, namely commercial activated carbon and activated carbon derived from rice husk. The resulting mixtures were then heated into a hydrothermal reactor at a temperature of 110°C for 5 hours. The results obtained were then characterized using FTIR, XRD and LCR meter. The results showed that Bi-O and Bi-O-Bi functional groups and α-Bi 2 O 3 had appeared in both products indicating bismuth oxide had been formed. Meanwhile, the results of electrical conductivity characterization for bismuth oxide/rice husk activated carbon composite is higher than bismuth oxide/commercial activated carbon composites. In the future, bismuth oxide/activated carbon composites can be applied as materials for producing battery electrodes; however, further research must be undertaken.
