At room temperature, dehydrating agent, concentrated sulfuric acid (H 2 SO 4 ) was used to form porous carbon (BAC) from bamboo waste shows good properties as CO 2 adsorbent. Selection of nano-CuO supported BAC produce composite materials with high total surface area and smaller pores size composite of 660.8 cm 2 /g and 2.7 nm. XRD data showed the support data to confirm the hydroxide phase formation as intermediate for carbonate and accelerate the CO 2 chemisorption reaction. Besides, the presence of BAC together with metal oxide can improve the CO 2 interaction physically on the surface and pores resulting the higher adsorption capability of 32.2 cm 3 of CO 2 per gram adsorbent. The combination of nano-CuO on BAC become a good adsorbent which can stimulate the CO 2 reduction programme as well as reduce the CO 2 emissions during BAC production.
