1P-659 : Electrons from Pt cathode facilitates NO reduction directly and indirectly at electro-scrubbing process

Because of direct reduction of NO possible on polycrystalline and Pt (111) phase, use of Pt cathode could be beneficial for enhanced reduc-tion of NO by mediated electrochemical reduction (MER) and direct electrochemical reduction (DER) processes instead of only MER. This work presents, a lab scale 50 and 400 cm2 working electrode area contained divided electrochemical cell was developed and used to generate [NiI(CN)4]3- in 10 M KOH using polycrystalline Pt cathode with capacity of 0.6 to 2 L scrubbing solution (catholyte). The electro-generated [NiI(CN)4]3- was concurrently scrubbed the feed gas NO at electroscrubbing. This NO reduction process was characterized and monitored by real time FTIR gas analyser.
