Embodiment 1
[0028] Weigh zinc sulfate heptahydrate and precipitating agent ammonium bicarbonate according to the molar ratio of 1:2, add pore-forming agent PEG with 2 times the quality of zinc sulfate heptahydrate and mix evenly with it, fully grind for 40 minutes and let it stand for a sufficient time (4 hours ), taken out, suction filtered, washed to remove the pore-forming agent, and dried to obtain porous zinc carbonate. Roast a certain amount of porous zinc carbonate at a temperature of 600°C for 2 hours to obtain porous zinc oxide.
Embodiment 2
[0030] Weigh manganese sulfate heptahydrate and precipitating agent ammonium bicarbonate according to the molar ratio of 1:2, add pore-forming agent PEG with 5 times the quality of manganese sulfate heptahydrate and mix evenly with it, fully grind for 40 minutes and let stand for enough time (4 hours ), taken out, suction filtered, washed to remove the pore-forming agent, and dried to obtain porous zinc carbonate. Roast a certain amount of porous manganese carbonate at a temperature of 600°C for 2 hours to obtain porous manganese oxide.
Embodiment 3
[0032] First, weigh the mixture of zinc sulfate heptahydrate and manganese sulfate according to the molar ratio of 1:2, then weigh the precipitant ammonium bicarbonate with 4 times the quality of the sulfate, add an appropriate amount of pore-forming agent PEG and mix it evenly, fully grind (40 Minutes) After standing for a sufficient time (4 hours), take it out, filter with suction, wash to remove the pore-forming agent, and dry to obtain a mixture of porous zinc carbonate and manganese carbonate.
