Claim Text:
1. A method for fixing metal onto a surface of a substrate, at least comprising the steps of: providing a substrate and a mercaptoalkylsilatrane compound, the structure of the mercaptoalkylsilatrane compound being as wherein R is a hydrogen atom or a protecting group, n is an integer between 0 and 30, Q1 and Q2 may be hydrogen, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, halogen, an alcohol group, an ether group, an ester group, or a functional group of alkyl, alkenyl, or alkynyl having silane, respectively and independently; using a solvent to dissolve the mercaptoalkylsilatrane compound; performing a condensation reaction of the mercaptoalkylsilatrane compound with a substrate to finish surface modification of the substrate; and performing a covalent bonding process to metal with the mercaptoalkylsilatrane compound which is already modified onto the surface of the substrate, so as to fix the metal onto the surface of the substrate.
