摘要： When fine metal particles of a nanometer size are handled in a state of colloidal particles, it is difficult to handle them and the range of the selection of the solvent to be used is limited. The invention offers a granular metal powder that is produced by the steps of (a) preparing a suspension liquid comprising (a1) water, an organic solvent, or a mixture thereof, (a2) metal particles having an average particle diameter of at least 1 nm and at most 100 nm, and (a3) an organic compound capable of being adsorbed on the surface of the metal particles and (b) removing the water, organic solvent, or mixture thereof by drying the suspension liquid and that has an apparent density of at least 1.0 g/ml and at most 5.0 g/ml. The granular metal powder can be handled as a dry metal powder and is readily redispersed in a solvent.

摘要： The present invention relates to a metal catalyst containing fine metal particles, characterized in that the fine metal particles have a particle diameter of 3 nm or less and also have a proportion of metallic bond state of 40% or more, which is ascribed by subjecting to waveform separation of a binding energy peak peculiar to the metal as measured by using an X-ray photoelectron spectrometer. The fine metal particles are preferably fine platinum particles. The fine metal particles are preferably supported on the surface of carrier particles by reducing ions of metal to be deposited through the action of a reducing agent in a reaction system of a liquid phase containing the carrier particles dispersed therein, thereby to deposit the metal on the surface of carrier particles in the form of fine particles. The proportion of metallic bond state of the fine metal particles is adjusted within the above range by reducing after deposition thereby to decrease the oxidation state.
