Ej. Grootendorst et al., THE ROLE OF THE MARS AND VAN KREVELEN MECHANISM IN THE SELECTIVE OXIDATION OF NITROSOBENZENE AND THE DEOXYGENATION OF NITROBENZENE ON OXIDIC CATALYSTS, Journal of catalysis, 157(2), 1995, pp. 706-712
The role of lattice oxygen atoms in the oxidation of nitrosobenzene to
nitrobenzene has been established by using isotopically labeled oxide
s and, in other experiments, O-18(2) as oxidant, It appeared that with
the most active catalyst, alpha-Mn3O4, the Mars and van Krevelen mech
anism (oxidation by lattive oxygen atoms) is the most important mechan
ism, On gamma-Fe2O3 and gamma-Al2O3, disproportionation of nitrosobenz
ene prevails. (C) 1995 academic Press, Inc.
