The invention provides a modified catalyst for gaseous-state elemental mercury oxidation and a preparation method of the modified catalyst, belonging to the technical field of mercury removal from smoke. The catalyst is the modified catalyst formed by loading a catalysis component manganese chloride, and a doping modification component ammonium molybdate on a catalytic carrier, wherein the total load of molybdenum, manganese and chlorine is 1.25-25 wt%, and the molar ratio of the three elements is (0.007-0.14): 1: 2. Experimental results indicate that via the preparation method, the three elements molybdenum, manganese and chlorine can be uniformly dispersed on the catalytic carrier to inhibit the grain agglomeration of the catalyst during the preparation process and form a more stable aggregate, thus effectively increasing the efficiency of oxidation for gaseous-state HgO; and the catalyst is very strong in catalytic oxidation performance and sulphur-resistant performance for the gaseous-state HgO in a temperature ranging from 100 to 200 DEG C, and long in endurance time; and the catalytic oxidation efficiency of converting the gaseous-state HgO to Hg<2+> is greater than 97%.
