摘要:
Provided is a hydrogen-storing carbon material with improved hydrogen storage capacity. The hydrogen-storing carbon material has a total pore volume of 0.5 cm 3 /g or more, and a ratio of a total mesoporous volume to a total microporous volume per unit weight of 5 or more. In addition, the hydrogen-storing carbon material may have a nitrogen content of 0.5 wt% or more and less than 20 wt%. In addition, the hydrogen-storing carbon material may have a stable potential of -1.28 V or more when a cathode current with respect to the hydrogen-storing carbon material is held at 1,000 mA/g in electrochemical measurement by chronopotentiometry involving using the hydrogen-storing carbon material in a working electrode in a three-electrode method.
摘要:
Provided are a carbon catalyst for hydrogen production having an excellent catalytic activity, a production method therefor, and a method of producing hydrogen using the catalyst. The carbon catalyst for hydrogen production is a carbon catalyst, which is obtained by carbonizing a raw material including an organic substance and a transition metal, the catalyst being used for hydrogen production by thermal decomposition of a hydrocarbon compound and/or an oxygen-containing organic compound. Further, the carbon catalyst for hydrogen production may be obtained by loading an alkaline earth metal on a carbonized material produced by the carbonization.
