Abstract
Manganese oxide octahedral molecular sieves are provided in which a portion of the framework manganese is substituted by at least one other metal, e.g., a transition metal.
Claims11
A manganese oxide octahedral molecular sieve which possesses a 2.times.2 tunnel structure and in which a portion of the manganese present in the framework structure of the molecular sieve is substituted by another metal.
A process for preparing a manganese oxide octahedral molecular sieve having a 2.times.2 tunnel structure and in which a portion of the manganese present in the framework structure of the molecular sieve is substituted by another metal, said process comprising heating a reaction mixture containing sufficient concentrations of manganese cation, metal cation other than manganese cation, counter cation and permanganate anion under acidic conditions and at a sufficient pressure and temperature to provide the manganese oxide octahedral molecular sieve.
