(680c) Development of Novel Nanoporous Carbon Material for CO2 Capture

The development of novel materials for efficient CO₂ capture and its exploitation towards sustainable energy is a very imminent approach, due to the glitches of CO₂ emission from diverse industries is directly associated with the issue of global warming. Existing amine absorption technology has several hitches, which are hazardous by products and a high-energy requirement for regeneration, thus research is ongoing worldwide for effective capture of CO₂ by solid adsorbents¹. In this context, carbon materials are explicitly promising for CO₂ adsorption at ambient conditions, because carbon materials are easily obtainable, economically viable, chemically and hydrothermally robust and also possesses high surface area. Concerning the efficacy of carbon materials for CO₂ capture, we have developed a novel hierarchically structured porous carbon material by templating with hierarchically porous template via CVD method.

Upon successful synthesis of hierarchical nanoporous carbon, an optimized procedure to etch the template is accomplished without any morphological collapse. FE-SEM images in Figure 1 displays the morphology of as-synthesized carbon and template etched carbon materials, demonstrating the same morphology, thus evidencing the preliminary success of this work. The hierarchical nanoporous carbon materials are well characterized by various scientific instrumentation techniques such as XRD, N₂ ads-des measurements, FE-SEM, EDAX, HR-TEM and TGA. Further work on N-doping in the synthesized carbon and its capability towards CO₂ adsorption is currently under progress and all the data will be delivered during the presentation.
