| Outline of Final Research Achievements |
Here we report a carbon-γ-Fe2O3 nanoparticle composite of mesoporous carbon (MCNC), a remarkable and magnetically separable adsorbent, for the radioactive material emitted by the Fukushima Daiichi nuclear power plant accident. Since this MCNC is remarkably high performance, magnetically separable, and a readily applicable technology, it would reduce the environmental impact of the Fukushima accident if it were used. We also describe a magnetically separable, mesoporous solid acid catalyst synthesized from MCNC. This catalyst exhibits a concentration of acid sites at least eight times that of conventional catalysts as well as greater acid strength. The activity of this novel catalyst for the hydrolysis of cellulose is improved by fifty percent compared to a conventional catalyst. Since it is magnetically separable, this material can be readily recovered and reused, potentially reducing the environmental impact of industrial processes to which it is applied.
