| Outline of Final Research Achievements |
In this work, we aimed at the synthesis of high-temperature CO2 adsorbents from nanosheets derived from MgAl double layered hydroxides, which will be potentially used to intensify the existing hydrogen production processes. In addition, we aimed at the synthesis of fiborous CO2 sorbents that can be readily molded into filters. As a result, we succeeded in preparing nanofiborous materials a few hundreds nm in diameter. In addition, through CO2 sorption experiments conducted in both batch and flow systems, we found that Mg/Al mixed oxides obtained by heat treatment in flowing nitrogen adsorbed CO2 up to 8-times higher than those obtained by heat treatment in flowing air. This research has brought important insights into how to improve the performance of Mg/Al mixed oxides as high-temperature adsorbents.
