原始语种摘要: Abstract(#br)The catalytic oxidation of toluene with ozone at room temperature was carried out over hierarchically ordered mesoporous catalysts (CeO 2 (meso), Mn 2 O 3 (meso), ZrO 2 (meso), and γ-Al 2 O 3 (meso)) and Al 2 O 3 with various textural properties and phases (γ-Al 2 O 3 (meso), γ-Al 2 O 3 (13 nm), and α-Al 2 O 3 ) to examine the effects of the nature of the catalyst on the catalytic activity. The catalysts were characterized by N 2 -physisorption measurements, powder X-ray diffraction, temperature programmed reduction, X-ray photoelectron spectroscopy and scanning transmission electron microscopy with energy dispersive spectroscopy. Among the ordered mesoporous catalysts, γ-Al 2 O 3 (meso) had the highest toluene removal efficiency because of its highest surface area and pore...
