Nitrogen oxides involved in exhaust from internal combustion system would like to be transformed to ammonia, which we call NTA catalytic system, directed under the Moonshot program. We first gave an example of 2 step NTA process to adsorb NOx selectively from the exhaust. Then, the concentrated NOx adspecies is desorbed by ramping temperature, and transformed to ammnonia with a high yield. In this presentation, we will explain our investigation so far.
