Support effect on complete oxidation of volatile organic compounds over Ru catalysts

Oxidation of nitric oxide to nitrogen dioxide over Ru catalysts

“…Particularly, the reduction peaks at c.a. 180 and 230 8C are attributed to the reduction of crystallized RuO 2 to Ru 0 , in well-dispersed form and bulk form, respectively [26,27]. The reduction peak at 125 8C in the low temperature range is attributed to the reduction of poorly crystallized or so-called amorphous bulk RuO x .…”

“…organic synthesis [19], partial oxidation of hydrocarbons [20], Fischer-Tropsch synthesis [21] and ammonia synthesis [22]. Recently, ruthenium catalysts have been applied in the reaction of wet air oxidation of various pollutants [23][24][25] and complete oxidation of volatile organic compounds [26]. The good redox behaviors of ruthenium catalysts have been proved in these reactions, and supported ruthenium materials are thus expected to be good catalysts for other oxidation reactions.…”

Catalytic Oxidation of Nitric Oxide to Nitrogen Dioxide on Ru-FAU

“…The reduction peaks at below 250°C should be ascribed to the reduction of different types of Ru oxides since the support materials cannot be reduced within this temperature range. For Ru-USY, two reduction peaks at 100°C and 130°C are observed, which can be ascribed to the reduction of highly dispersed amorphous RuO 2 and bulk amorphous RuO 2 [19,20], respectively. As for RuNaY, the reduction of highly dispersed amorphous RuO 2 and bulk amorphous are observed at higher temperature than that on Ru-USY, e.g., at 120°C and 155°C, respectively.…”

Influence of Catalyst Pretreatments on Propane Oxidation Over Ru/γ-Al2O3

“…Ruthenium has been applied in oxidation of carbon monoxide [25], partial oxidation of methane [24], ammonia [26], alcohols [27], amines [28] and others [29]. Very recently, oxidation of VOCs such as propene and toluene [15], as well as toluene, ethyl acetate, acetaldehyde, and ortho-xylene [30] over Ru catalysts have been investigated.…”
