1. A method of preparing a catalyst for synthesizing dimethyl ether or methylacetate from synthetic gas, the method comprising:
adding a silica source, an alumina source, an organic template material, and a structural derivative material to a basic aqueous solution to prepare a precursor mixed solution;
synthesizing a nanosheet ferrierite zeolite (FER) by hydrothermal synthesis of the precursor mixed solution; 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;
wherein the structural derivative material includes pyrrolidine, piperidine, or a combination thereof; and
wherein the silica source and the aluminum source are added in a mole ratio of about 5:1 to about 30:1.
