Abstract

The present invention relates to a substrate having an organic metal complex bonded on the surface thereof, which is prepared by the vapor deposition of a sulfur atom onto a substrate followed by bonding of an organic metal complex such as tetrakis-triphenylphosphine palladium [Pd(PPh3)4] to the surface of the substrate; a substrate bonded transition metal catalyst using said substrate; and a method for the preparation thereof. The above substrate and metal catalyst allow the solution of some problems with respect to the safety and stability of an organic metal complex in its use, the removal of trace amounts of metals in a reaction product, waste water treatment and the like.
