Catalysis of Organic..

Yamauchi 165These fine particles were not newly formed but already existed as skeletal particles.Similar dispersion of ultra fine particles may occur in SPS by heating in vacuum.Each particle was composed of a single crystal as shown in high resolutiontransmission microscopy (Fig.17).Concluding remarksSome examples of new Raney® skeletal materials have been introduced by applyingmetastable processing to form their precursors. Applying these new materials tovarious organic reactions can lead to better catalytic results. The potential for routesto improved Raney® catalysts is thereby demonstrated.AcknowledgementsThis work was supported by the Japan Ministry of Education and Science, theHosokawa Powder Technology Foundation, Samsung Co.
