The present invention relates to a catalyst for dehydration of a primary alcohol, a method of preparing the same, and a method of producing an alpha-olefin using the same. The catalyst for dehydration of a primary alcohol according to the present invention has an excellent catalyst stability while having an excellent activity with respect to dehydration, and a high turnover frequency, such that a linear alpha-olefin with high purity may be produced with a high selectivity even in a case where a relatively small amount of a cocatalyst is added as compared with a homogeneous catalyst system.

The present invention relates to a method for preparing a catalyst comprising a ruthenium-containing catalyst layer highly dispersed with a uniform thickness on a surface of a substrate having a structure, which comprises first aging a mixed solution of a ruthenium precursor-containing solution and a precipitating agent to form a ruthenium-containing precipitate seeds, secondarily aging the first aged mixed solution to grow the seeds thereby forming ruthenium-containing precipitate particles, and then contacting the particles with a substrate to deposit the particles on the surface of the substrate. Since the catalyst has a structure in which the round shaped ruthenium-containing precipitate particles are piled to form the ruthenium-containing catalyst layer, it has a large specific surface area. Thus, the catalyst may exhibit excellent catalytic performance in various reactions for producing hydrogen using a ruthenium catalyst.
