Abstract. Binuclear iron clusters were constructed successfully in cavities of HY Zeolite by surface organometallic chemistry (SOMC) of ferrocene. UV–visible diffuse reflection (UV–vis DRS), X-ray absorption fine structure (XAFS), electron paramagnetic resonance (EPR), and infrared (IR) spectroscopies were used to characterize the structure of the formed binuclear iron clusters. The res…
