Novel catalytic function of stable 0-valent active species generated from base metal supports

采用沉积-沉淀法或共沉淀法负载金、钯等贵金属，氢还原对贱金属还原的促进作用。与通常的催化剂相比，加氢、氢氨甲基化、酰胺羰基化、FT反应等能够在较温和的条件下进行。此外，以镍为载体时，形成了Au-Ni合金，具有较高的脱苄活性。

Promotion effect of reduction of base matals was obserbed by the hydrogen reduction in the presence of noble metals including gold and plladium, ehich were supported by deposition-precipitation or co-precipitation method. Hydroformylation, hydroaminomethylation, amidocarbonylation, FT reaction, etc. were able to carried out under milder conditions compared to usual catalysts. In addition, when nickel was used as support metal, Au-Ni alloys were formed and those have high activities for debenzylation.
