    Abstract: 본 발명은 입경이 3㎚이하인 동시에, X선 광전자분석장치를 이용해서 측정된 금속 고유의 결합에너지 피크를 파형 분리함으로써 얻어지는 금속결합상태의 비율이 40%이상인 금속 미립자를 함유한 금속촉매이다. 금속 미립자로서는 백금 미립자가 바람직하다. 또, 금속 미립자는 담체 입자를 분산시킨 액상의 반응계 중에서 해당 금속 미립자의 기초가 되는 금속의 이온을 환원제의 작용에 의해 환원해서 담체 입자의 표면에 미립자 형상으로 석출시킴으로써, 담체 입자의 표면에 담지되는 것이 바람직하다. 또, 상기 금속 미립자는 석출 후에 환원해서 산화상태를 저하시킴으로써, 금속결합상태의 비율이 상기의 범위로 조정된다.

    Abstract: A metal catalyst containing fine metal particles, characterized in that the fine metal particles have a particle diameter of 3 nm or less and have a proportion of a metal in the state of a metallic bonding of 40 % or more, which proportion is determined through subjecting a peak ascribed to the bonding energy inherent in a metal being measured by an X- ray photon analyzer, to a wave form separation. Platinum fine particles are preferred as the above fine metal particles. Preferably, the metal particles are carried on the surface of carrier particles by a method comprising reducing a metal ion generating the metal particles by the action of a reducing agent to thereby precipitate the metal in the form of fine particles on the surface of carrier particles. Further, the above fine metal particles can have the above-mentioned proportion of a metal in the state of a metallic bonding, through the decrease of its oxidation state by the reduction after precipitation. ® KIPO & WIPO 2007

    Abstract: Nanometer-size fine metal particles in a colloidal state have poor handleability and the choice of solvents usable therewith is limited. A granular metal powder is provided which is characterized by being obtained from a solution comprising water or an organic solvent, an organic compound capable of being adsorbed onto metal particle surfaces, and metal particles having an average particle diameter of 1 to 100 nm by removing most of the water or organic solvent. It is characterized also by having a bulk density of 1.0 to 5.0 g/mL. This granular metal powder can be handled in a dry state as metal particles and can be easily redispersed in solvents.
