The preferential generation of protective Al 2 O 3 oxide scale on TiAl alloys is affected not only by the surface roughness, but also dependent on the oxidation environment. It has been demonstrated that oxidation in low oxygen partial pressure promotes the selective oxidation of Al to form protective Al 2 O 3 scale, although Al 2 O 3 and TiO 2 have almost the same thermodynamic stabilities.

The preferential reactions of peroxynitrite in vivo include those with carbon dioxide, thiols and metalloproteins; its homolysis represents only 1 % of its fate. To note, carbon dioxide accounts for a significant fraction of peroxynitrite consumption leading to the formation of strong one-electron oxidants, carbonate radicals and nitrogen dioxide.

Preferential Oxidation

Preferential Oxidation Preferential oxidation is one of the catalytic processes that allow to remove small amounts of CO to reach parts per million (ppm) levels form hydrogen-rich streams (Liu et al., 2012b), by selective oxidation of carbon monoxide. From: Bioenergy Systems for the Future, 2017

Identification of CuO Species in High Surface Area

Nanosized CuO−CeO2 catalysts with high surface area (90 m2 g-1) were prepared by a modified citrate sol−gel method with incorporation of N2 thermal treatment. CO temperature-programmed reduction results indicated that there are three CuO species in the catalyst, namely, the finely dispersed CuO, the bulk CuO, and the Cu2+ in the CeO2 lattice. Using CO oxidation as a model reaction
