Embodiment 1
[0018] Example 1: In an 80°C water bath, mix Birnessite-type manganese oxide, copper nitrate, and cerium nitrate according to the Cu:Ce:Mn molar ratio of 0.05:0.05:1, stir vigorously, wash and filter, and bake at 110°C for 12 h Finally, a black solid powder was obtained, and the powder was roasted in an air atmosphere at a rate of 1 °C / min to 200 °C for 10 h to prepare a Cu and Ce doped manganese oxide catalyst.
Embodiment 2
[0019] Example 2: In a 40°C water bath, mix Birnessite-type manganese oxide, copper chloride, and cerium nitrate according to the Cu:Ce:Mn molar ratio of 0.05:0.05:1, stir vigorously, wash and filter, and dry at 110°C for 12 After h, a black solid powder was obtained, and the powder was calcined in an air atmosphere at a rate of 5 °C / min to 700 °C for 1 h to prepare a Cu and Ce doped manganese oxide catalyst.
Embodiment 3
[0020] Example 3: In a 60°C water bath, mix Birnessite-type manganese oxide, copper acetate, and ammonium cerium nitrate at a Cu:Ce:Mn molar ratio of 0.05:0.05:1, stir vigorously, wash and filter, and bake at 110°C for 12 After h, a black solid powder was obtained, and the powder was calcined in an air atmosphere at a rate of 10 °C / min to 700 °C for 3 h to prepare a Cu and Ce doped manganese oxide catalyst.
