Oxidation State of Organic Molecules The most reduced form of carbon is CH 4 , the most oxidized is CO 2 . Thus the oxidation state of a one-carbon fragment is unambiguous and defined by the number of C-H bonds that have been replaced by C-X bonds, where X = any electronegative eleme...

The material exposed at 950 °C showed a significant formation of TiO2 with a small amount of Al2O3 and high number of voids; the formation of Cr2O3 at 950 °C was inhibited mainly due to the formation of volatile CrO3 or CrO2(OH)2 phase....
One suggestion for the loss of protection against further oxidation is the volatilization of Cr by the formation of volatile Cr-bearing species such as CrO3 [27, 28] and/or oxy-hydroxide CrO2(OH)2 [26, 29]. The volatilization of Cr leads to its depletion in the oxide layer and the ...
For example, reaction of barium nitrate or magnesium nitrate with chromium oxide enhances catalytic activity whereas substitution of molybdenum oxide for chromium oxide has a detrimental affect on catalytic activity. One of the preferred binder reactions is: Ba(NO3)2 + CrO3 + H2 O⇋BaCrO4 + 2...
