Abstract
At room temperature, dehydrating agent, concentrated sulfuric acid (H2SO4) was used to form porous carbon (BAC) from bamboo waste shows good properties as CO2 adsorbent. Selection of nano-CuO supported BAC produce composite materials with high total surface area and smaller pores size composite of 660.8 cm2/g and 2.7 nm. XRD data showed the support data to confirm the hydroxide phase formation as intermediate for carbonate and accelerate the CO2 chemisorption reaction. Besides, the presence of BAC together with metal oxide can improve the CO2 interaction physically on the surface and pores resulting the higher adsorption capability of 32.2 cm3 of CO2 per gram adsorbent. The combination of nano-CuO on BAC become a good adsorbent which can stimulate the CO2 reduction programme as well as reduce the CO2 emissions during BAC production.
