Structural Feature and Catalytic Performance of Cu Species Distributed over TiO2 Nanotubes

摘要: Copper oxide was deposited on tubular TiO2 via Cu2+ introduction into a titanate nanotube aggregate followed by calcination. The has layered structure allowing Cu intercalation and can readily transform anatase calcination for condensation of the constituting layers. activity catalysts, with content 2 wt %, in selective NO reduction NH3 compared those other % Cu/TiO2 catalysts using nanoparticles as support. species supported nanotubes showed higher than nanoparticles. X-ray absorption near-edge (XANES) analysis that all supports are +2 state. Extended fine (EXAFS) investigations these reflected degrees CuO dispersion dissolution lattice catalysts. Absence bulk detection temperature-programmed the...
