Highly dispersed MoO 3 on SiMCM ‐41 was applied to the dehydration of 2‐butanol. MoO 3 / MCM ‐41 catalysts were prepared using a modified atomic layer deposition method. The structural characteristics of MoO 3 supported on SiMCM ‐41 were examined by inductively coupled plasma spectrometry, nitrogen adsorption, X‐ray photoelectron spectroscopy, and X‐ray diffraction. The textural characteristics of SiMCM ‐41 were retained after loading with MoO 3 . Ammonia temperature‐programmed desorption and Fourier transformation infrared spectroscopy of adsorbed pyridine showed that Lewis acid sites were formed on the MoO 3 / MCM ‐41 catalysts. Among the MoO 3 / MCM ‐41 catalysts, the MoO 3 (16.4 wt %)/ MCM ‐41 catalyst showed the highest catalytic activity for butene synthesis from 2‐butanol dehydration due to the largest number of acid sites.
