Abstract
An exemplary method for producing a catalyst is provided where the catalyst includes a catalyst support on which a metallic compound is loaded. An impurity content of the catalyst can be in a range of approximately 0.01 mass % to 0.15 mass %. In particular, the exemplary method can include pre-treating the catalyst support to lower an impurity concentration of the catalyst support, and loading the metallic compound on the catalyst support after the pretreatment procedure.
