Abstract: In a method of manufacturing a bimetallic catalyst for reductively decomposing nitrate nitrogen, a powder including a trivalent iron oxide, a powder including a trivalent iron oxyhydroxide powder or a combination thereof is mixed in an aqueous solution. A copper precursor and a palladium precursor are mixed in the aqueous solution to form a precursor mixture. The precursor mixture is dried. The dried precursor mixture is fired at a temperature from about 300° C. to about 450° C. to form a fired product. The fired product is reduced by a reducing agent. A hydrochloric acid solution is mixed in the aqueous solution, or mixed with the copper precursor or the palladium precursor.
Abstract translation: 在制造用于还原性分解硝态氮的双金属催化剂的方法中，将包含三价氧化铁的粉末，包含三价羟基氧化铁粉末或其组合的粉末在水溶液中混合。 将铜前体和钯前体在水溶液中混合以形成前体混合物。 将前体混合物干燥。 干燥的前体混合物在约300℃至约450℃的温度下焙烧以形成焙烧产物。 烧制的产品被还原剂还原。 将盐酸溶液在水溶液中混合，或与铜前体或钯前体混合。
