Abstract
Provided is a method for producing a NOx removal catalyst for high-temperature exhaust gas, comprising: calcining a mixture comprising ZrOand TiOwith a ZrOcontent ratio of 15% by weight to 55% by weight at 500±15° C. to obtain a composite oxide support; and supporting tungsten oxide on the composite oxide support, followed by calcination at 650±15° C. to obtain a powder catalyst.
