Abstract
The invention discloses a sponge-like structure gadolinium oxide doped cerium zirconate denitration catalyst and a preparation method and application thereof.According to the catalyst, cerium zirconate micron fibers serve as a carrier, gadolinium oxide serves as an active component, and the microstructure of the catalyst is of a sponge-like structure; by taking the mass of the carrier as a reference, the mass percentage of the active component is 3-10%. The catalyst is environment-friendly, high in denitration activity at low temperature, simple in preparation process and wide in market application prospect.
