| Research Abstract |
The present research aims at making a catalytic system to allow molecular splitting of nitrogen for molecular conversion of organic molecules. One-step multi-electron transfer complexes were applied for the multi-electron reduction of nitrogen via a μ-dinitrido type complex.
The four-electron reduction of oxygen catalyzed by a μ-oxo divanadium complex were expanded to the μ-dinitrido complex for the reduction of nitrogen. An effective complex, Nb diethyldithiocarbamate complex was found which formed the desired μ-dinitrido complex upon the reaction with nitrogen. Electrocatalytic reduction of nitrogen was established using the complex.
The N-N bond splitting reaction was investigated using MO calculations and in-situ electrochemical Raman spectroscopy, which revealed that the multi-electron transfer is fostered by the catalytic system.
