More Information
Summary:The invention discloses a modified and activated transition metal molecular sieve and application thereof.According to the molecular sieve, a transition metal-doped molecular sieve serves as a matrix, a heteroatom element P is introduced into the matrix for modification, or the matrix is modified through a substance containing an active functional group, so that the active functional group is grafted to the matrix, and the modified and activated transition metal molecular sieve is obtained. The active functional group is at least one of NH <->, NH2 <-> or COOH <->; the transition metal doped molecular sieve matrix comprises a substance mSiO2: XO according to the following chemical composition molar ratio, X is a divalent transition metal, and the molar ratio m of SiO2 to XO is equal to 10-30. According to the present invention, the active functional group species performs the functional regulation on the molecular sieve skeleton pore channel, such that the fine regulation on the skeleton pore channel polarity
