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(PPh.sub.3).sub.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.
