| Research Abstract |
Synthesis of Ni-pincer complexes which are expected to work as an oxidation catalyst of methanol was investigated. In this work, Ni-pincer complexes were synthesized and their electrochemical properties were clarified. Pincer-type ligands show strong electron-donating ability to the centered metal, therefore they are expected to shift the oxidation potential of the complex lower. (N,C,N)- and (S,C,N)-type Ni-pincer complexes were synthesized, and their electrochemical properties were measured by cyclic voltammetry. Production of the Ni complex which has lower oxidation potential was succeeded by treatment of a base to a Ni complex which has two secondary thioamides in the arm of the pincer ligand. Electrochemical oxidation of methanol using this Ni-pincer complex as a catalyst was tried. As a result, oxidation of methanol was progressed at ca. +0.8 V (vs. Ag+/Ag).
The method of fixing the catalyst on an electrode was also examined.
