The invention relates to an electrochemical cell useful in the reduction of nitro compounds. The
cell comprises: in combination a novel cathode consisting of Ti/ceramic TiO2 and the said cathode
sheet being coated with a solution consisting of titanyl acetyl acetonate or titanyl butanoate, nitric
acid or hydrochloric acid, water and isopropanol as herein described, lead as anode, a porous
diaphragm, the nitro or dinitro compound in sulphuric acid as the catholyte and sulphuric acid as
the anolyte.
