孔を有する発泡金属にして触媒を構成している。BACKGROUND OF THE INVENTION Porous metal catalysts having a three-dimensional skeleton structure are known in the art. For example, the surface of a foamed urethane foam is electroplated with Ni or the like, and then the urethane foam is burned off to form a foamed metal having communicating holes to form a catalyst.
一明が解′(シようとL乞l」劇
従来の発泡金属においては、三次元骨格の断面がウレタ
ンフオームの焼去後に空洞とIノで残存づる。In conventional metal foam, the cross section of the three-dimensional skeleton remains in the form of cavities and holes after the urethane foam is burned out.
発泡金属のみで成りたっているため、骨格構造の強度が
小ざくなる欠点があった。Since it was made only of foamed metal, it had the disadvantage that the strength of the skeletal structure was reduced.

た。In order to achieve this, a base material with a three-dimensional skeleton structure is constructed of glass-like J-bonds, and a thin film of P is applied to the surface of the base material, without meeting certain conditions.
t, Pd, △1'' or A(+ noble metal was coated.

The strength of Composite 1 can be greatly increased.
また、貴金属の薄膜の厚みを小さくしても、強度上の問
題が生じない。Further, even if the thickness of the noble metal thin film is made small, no strength problems arise.

タンフオームに樹脂(たとえばフルフリルアルコール重
合物)を付着さぜる。A resin (for example, furfuryl alcohol polymer) is attached to a porous soft polynisder urethane foam with a three-dimensional skeleton structure on a pointed plate.
たどえば、ウレタンフオームにフリフリルアルコール手
合物を含浸させる操作において、目詰まりがなく、かつ
均一に脱液が行えるJニうに遠心脱液装置を用いて含浸
するのが好ましい。For example, in the operation of impregnating the urethane foam with the frifuryl alcohol compound, it is preferable to impregnate the urethane foam using a centrifugal dewatering device that does not cause clogging and can uniformly remove the fluid.
そのあと、150’Cで樹脂を乾燥硬化させる。しかる

づる。Thereafter, the resin is dried and cured at 150'C. Thereafter, in a non-oxidizing atmosphere (e.g. nitrogen atmosphere) 9
Cover and bake at 50°C. By this firing, the urethane foam is carbonized, the resin becomes glassy carbon, and a three-dimensional glassy carbon skeleton structure base material having communicating holes in the skeleton is formed.
なお、前述の含浸→硬化→焼成の工程を複数回くり返し
たり、焼成後に純化のために塩素ガスと接触させながら
約2300 ’Cで加熱してもにい。In addition, the above-mentioned impregnation → hardening → firing process may be repeated several times, or after firing, the material may be heated at about 2300'C while being brought into contact with chlorine gas for purification.

If it is larger than a human, the crystallites will be too large, resulting in a decrease in strength. In addition, the specific gravity of the butanol immersion method is 1.7.
If it is larger than 0q/CC, manufacturing becomes extremely difficult.

d. Form a thin film of AU or Ag to coat the surface of each skeleton. If the thickness of the thin film is less than 20 μm, the strength of the two-dimensional skeleton structure will not be sufficient, and if it exceeds 2 mm, the voids in the three-dimensional skeleton structure will decrease.
m is preferred. Methods other than sputtering (for example, plasma method, electrolytic plating method, non-electrolytic plating method, CVD method)
J: It is not possible to form a thin film by a method such as a method.
