Page 3) introduces three-way catalysts for automobiles, catalysts for treating exhaust gas from factories, etc. However, heat is required for these catalysts to exert their full functions, and even low catalysts can be used.
Heat of 0 to 400 ° C is required. For example, in the dry ammonia selective catalytic reduction method used for treating exhaust gas in a factory, ammonia is mixed with exhaust gas containing NOx to obtain 200
NOx is reduced to nitrogen and water by passing through a catalyst layer at 400 ° C. In such a method, since a heating device is required because it requires heat, there is a problem that the device is large and energy cost for heating is required, and there is a problem that usable places are limited. There is also a problem that dangerous ammonia and hydrocarbons are required as a reducing agent.
