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 results show that the majority...
The adsorption and transformation of cyclopentadiene on HY and HZSM-5 zeolites were investigated by infrared (IR) spectroscopy and temperature-programmed desorption (TPD). The stoichiometric formation of monomeric cyclopentenyl carbenium ions (C 5 H +7 ) was observed on the acidic sites in the supercages of zeolite HY and in the channels of zeolite HZSM-5 at room temperature,...
