Abstract

The catalytic Fe/γ-Al₂O₃ system in air, CO, and H₂ atmospheres has been studied in the temperature range of 293–773 K. In the initial state, the system contains at least two Fe³⁺ paramagnetic forms with close values of isomeric shift and different quadrupole splittings. In this system, iron is reduced to the Fe²⁺ state in an atmosphere of СО and Н₂ at 423–773 K. The latter state also exists in at least two forms. The processes occurring in the system and the nature of the found iron forms are discussed.

摘要

催化铁/γ-Al系₂ ö ₃在空气中，CO和H系统₂个大气压已在温度范围293-773 K的被研究在初始状态下，系统包含至少两个的Fe ³⁺与顺磁的形式异构位移的接近值和不同的四极分裂。在这个系统中，铁被还原成铁²⁺状态СО和Н气氛₂在423-773 K.后者状态也存在于至少两种形式。讨论了系统中发生的过程和发现的铁形态的性质。
