| abstract |
One aspect of the present invention relates to a catalyst composite containing a specifically defined carbon-based support containing a carbonaceous material and a metal catalyst. For example, the carbon-based support may have a total pore surface area of about 800 m 2 / g or more and about 2,000 m 2 / g or less, wherein the surface area of the micropores is equal to the total pore surface area. It should be about 20% or less. Alternatively, the carbon-based support may have a total pore volume of at least about 0.75 cc / g, wherein the micropore volume is no more than about 15% of the total pore volume. To. In yet another aspect of the present invention, the phosphorus content of the carbon-based support may be about 0.75% by weight or less. In yet another aspect of the invention, methods for making and using the catalyst composite are disclosed. |
