Abstract
The Fe/Mo/partially deboronated borosilicate molecular sieve catalyst prepared by the chemical vapor deposition (CVD) method was active for the selective formation of phenol by gas-phase N2O oxidation of benzen e. The impregnated counterpart exhibited lower activity than the CVD c atalyst. The borosilicate molecular sieve itself also was active. Two mechanistic paths are postulated based on reactive oxygen species such as O-, which can be generated via interaction of N2O with the iron si tes in the CVD-borosilicate molecular sieve catalyst, or OH+, which ca n be generated by Bronsted sites on the borosilicate molecular sieve i tself.
