Abstract
Official abstract text for this publication.
Provided is a hydrogen isotope adsorbent with differential binding properties and including mesoporous silica doped with fluorine.
First claim
Opening claim text (preview).
What is claimed is: 1. A manufacturing method of a hydrogen isotope adsorbent comprising the following steps: (a) adding mesoporous silica and a fluorine compound to a solvent to generate a mixture; and (b) heat-treating the mixture, wherein in step (b), the mixture is first heat-treated at 100 to 140° C. for 20 to 28 hours, and then the mixture is second heat-treated at 100 to 140° C. for 3 to 7 hours. 2. The manufacturing method of the hydrogen isotope adsorbent of claim 1 , wherein the mesoporous silica is MCM-41. 3. The manufacturing method of the hydrogen isotope adsorbent of claim 2 , wherein the solvent is isopropanol. 4. The manufacturing method of the hydrogen isotope adsorbent of claim 2 , wherein the fluorine compound is ammonium fluoride (NH 4 F). 5. The manufacturing method of the hydrogen isotope adsorbent of claim 2 , wherein in step (a), the content of the fluorine compound is 20 to 100 parts by weight with respect to 100 parts by weight of the MCM-41. 6. The manufacturing method of the hydrogen isotope adsorbent of claim 5 , wherein in step (a), the content of the fluorine compound is 40 to 60 parts by weight with respect to 100 parts by weight of the MCM-41. 7. The manufacturing method of the hydrogen isotope adsorbent of claim 2 , wherein in step (a), 1.5 to 1.8 g of the MCM-41 per 100 mL of the solvent is added.
