Abstract

A new convenient method for the synthesis of hydrated tris 2, 2'-bipyridine dichloride ruthenium II complex has been developed. We introduced the chlorosulfonic acid as a chlorinating reagent during our synthetic process which replace the hexafluorophosphate radical of the [Ru bpy 3] PF6 2 complex with chloride, form hydrated Tris [Ru bpy 3] Cl 2 complex. The corresponding complex is characterized with UV-Visible, IR, CV, 1 H and C 13 NMR spectroscopic technique. The synthesized hydrated ruthenium complex was then checked as an electrocatalyst for the reduction of carbon dioxide in a designed electrolytic cell. The carbon dioxide gas in the aqueous solution of Tris 2, 2'-bipyridine ruthenium II dichloride catalyst, at the potential of 1.5 V reduced to methane gas, examined with FTIR spectrometer
