Aluminum Distribution in Ferrierite Zeolites Influences the Performance of Methane Oxidation.

ABSTRACT: Transition-metal-free aluminosilicate FER-type zeolite has been demonstrated to effectively catalyze methane to methanol using N₂O as the oxidant with distorted tetra-coordinated aluminum (Al_IV-2) and penta-coordinated aluminum (Al_V) as potential active sites. However, the specific effects of Al distribution on the active Al species have not been thoroughly investigated. Herein, aluminosilicate FER-type zeolites with controllable Al distribution were developed. Al distribution, including the arrangement and location of Al atoms, was characterized using ²⁷Al MQMAS/MAS and ²⁹Si MAS NMR spectra. The arrangement of aluminum, particularly the isolated Al and paired Al in as-synthesized samples, influenced the proximity between oxidative and
