CuO modified vanadium-based SCR catalysts for Hg oxidation and NO reduction.

The catalytic performance of Hg oxidation over vanadium-based SCR catalysts modified by different addition amounts of CuO was investigated. All catalysts were prepared by impregnation method and characterized. The 7% Cu/VWTi exhibited high Hg oxidation as well as a desired NO removal efficiency at 280-360 °C.

Visible-Light Photocatalytic Activity of Fe and/or Ni Doped Ilmenite Derived-Titanium Dioxide Nanoparticles.

Pure TiO₂ nanoparticles and ones doped with Fe and/or Ni were successfully prepared by a co-precipitation method from ilmenite. The samples were structurally characterized by XRD, XPS, FT-IR, UV-vis, SEM, EDX, AAS and BET measurement. The XRD results showed that all samples were anatase TiO₂, and no characteristic peaks of dopants were observed.

Simultaneous removal of SO and NO from flue gas by wet scrubbing using a urea solution.

Nitrogen oxides (NO) and sulfur dioxide (SO) are major air pollutants, so simultaneously removing them from gases emitted during fossil fuel combustion in stationary systems is important. Wet denitrification using urea is used for a wide range of systems. Additives have strong effects on wet denitrification using urea, and different mechanisms are involved and different effects found using different additives.
