Abstract

The present disclosure provides a method of preparing a catalyst for synthesizing dimethyl ether or methylacetate from synthetic gas that includes preparing a nanosheet ferrierite zeolite (FER), and co-precipitating the nanosheet ferrierite zeolite and a precursor of a Cu—Zn—Al-based oxide (CZA) to obtain a hybrid CZA/FER catalyst.
