通过水热法合成了骨架含铁的杂原子丝光沸石,采用XRD,FT-IR及TPR等表征技术确认铁进入了分子筛骨架.利用XAFS技术对分子筛中铁的精细结构和配位环境进行了表征和计算,近边吸收的Fe-K边前跃迁证实铁在分子筛骨架中位于四面体配位环境中,与邻近原子存在共价键作用;铁-氧配位键长为0.188～0.189nm. The iron-containing heteroatom mordenite was synthesized by hydrothermal method, and the XRD, FT-IR and TPR techniques were used to confirm that iron entered into the molecular sieve framework. The fine structure and coordination environment of iron in molecular sieve were characterized by XAFS Calculated, near the edge of the absorption of Fe-K edge transition confirmed iron in the framework of molecular sieve coordination tetrahedral coordination environment, covalent bonding with neighboring atoms; iron-oxygen coordination bond length of 0.188 ~ 0.189nm.
