Title:
METHOD FOR PREPARING BIMETALLIC CATALYST WITH HIGH NITRATE REMOVAL EFFICIENCY AND NITROGEN SELECTIVITY, AND CATALYST PREPARED THEREBY
Document Type and Number:
WIPO Patent Application WO/2015/122561
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a catalyst decomposing nitrates by a reduction reaction in which iron(III) oxide or iron(III) oxide-hydroxide are used as a raw material such that a copper precursor and a palladium precursor are supported in hematite, wherein a hydrochloric acid aqueous solution is mixed in a step of preparing an aqueous solution by mixing the raw material or in a step of mixing the copper precursor and the palladium precursor with the aqueous solution.
