Global warming was becoming more and more of a concern as a result of the continuing emission of a major greenhouse gas, carbon dioxide (CO2), which is generated from fossil fuel combustion. However, fossil fuels were demanded as an essential resource. Therefore, it is essential to technology of reduced CO2 emission. In this study, we converted graphite oxide (GO) with amine groups from polyethylenimine due to improve a new CO2 adsorbent. The polyethylenimine-impregnated GO was then investigated for CO2 adsorption. Consequentially, the CO2 chemisorption capacity was developed by increasing of polyethylenimine contents. And the selectivity improves than pristine GO, which indicated little N2 affinity. |
