Abstract: Provided are a V-Mn-Sb-TiO2 catalyst, a method of fabricating the catalyst, a heat recovery steam generator including the catalyst, and a method of eliminating yellow plume using the catalyst. The catalyst eliminates nitrogen oxides. The catalyst is supported with vanadium, manganese, and antimony on a titania carrier, wherein the vanadium is contained in an amount of about 1 wt% to about 5 wt% with respect to the total weight of the catalyst, the manganese is contained in an amount of about 0.5 wt% to about 20 wt% with respect to the total weight of the catalyst, and the antimony is contained in an amount of about 0.5 wt% to about 5 wt% with respect to the total weight of the catalyst.
