Abstract
The present invention provides a method of decomposing an ammonia gas, including the step of decomposing an ammonia gas, into a nitrogen gas with use of a composite material as a catalyst. The composite material has a carrier made mainly of carbon and at least one kind of an active element which is supported by the carrier and selected from alkaline earth metals and transition metals.
Claims14
A method of decomposing ammonia gas, comprising the step of:
- decomposing an ammonia gas into a nitrogen gas with use of a composite material as a catalyst, said catalyst comprising a carrier consisting essentially of carbon and at least one active element supported by said carrier and selected from the group consisting of alkaline earth metals and transition metals, wherein said composite material is at least one of:
- a material prepared by heating an organic material containing at least one element selected from the group consisting of alkaline earth metals and transition metals so as to thermally decompose said organic material;
- and
- a material prepared by heating a mixture of at least one element selected from the group consisting of alkaline earth metals and transition metals and an organic material so as to thermally decompose said organic material.
