摘      要：Single molecule catalysis is very powerful in revealing catalytic mechanism at the single molecule *** fluorescent molecule is always necessary to take part into the catalysis directly in previous *** order to study the single molecule electro-catalysis of non-fluorescent molecule（SMECNFM） on nanocatalyst, we couple the SMECNFM with a single molecule fluorescence reaction. A certain number of fluorescent molecules will be generated and detected when the SMECNFM happens. Through this method, we can detect the electro-oxidation reaction of one HCOONa molecule. The stability of Pt nanocatalyst supported on active carbon is studied at the single molecule level by this method. This paper also provides a general way to make ultra-sensitive sensor, and to study the SMECNFM for the molecules,such as formic acid, hydrogen, oxygen, etc., on single nanoparticle.
