The photocatalytic degradation of nitrogen monoxide (deNOx) in the gas phase was investigated in a continuous reactor using a strontium titanate-based semiconductor, CaAl2O4:(Eu, Nd)/Cr-doped SrTiO3, and CaAl2O4:(Eu, Nd)/oxygen vacancy-induced SrTiO3 catalysts. Cr doping and oxygen vacancies generation could narrow the band gap of SrTiO3 and affect the photocatalytic performance to varying degrees...
Nitrogen-doped titanium oxide (TiO 2−x N y ) nanocrystalline with different phase of anatase, rutile or brookite was coupled with CaAl 2 O 4 :(Eu, Nd) particles by planetary ball milling treatment. The effect of phase structures on the persistent photocatalytic activity of a CaAl 2 O 4 :(Eu, Nd)/TiO 2−x N y composite was evaluated...
