Abstract: A denitrification catalyst using ceramic nanotubes grown on a porous metal structure, including: a porous metal structure having a plurality of pores formed between metal supports such that exhaust gas penetrates through the pores in multiple directions; ceramic nanotubes grown on the porous metal structure through anodic oxidation; and an active material uniformly and highly dispersed as a nano-thin film layer on inner and outer surfaces of the ceramic nanotubes through a deposition or supporting process.
