Embodiment approach 1
[0023] First prepare a mixed aqueous solution of zinc acetate and manganese acetate with a concentration of 0.5-1M, wherein the molar amount of manganese acetate dihydrate added is equivalent to 10% of the molar amount of zinc acetate dihydrate added; Add a stable dose of urea to the aqueous solution, then slowly add ethanol and magnetically stir until the urea is completely dissolved to obtain a clear solution A; then add NaOH to the clear solution A to adjust the pH of the system to 14 to obtain a brown sol system B; The brown sol system B was transferred to a polytetrafluoroethylene-lined hydrothermal kettle, and the hydrothermal reaction was carried out at 160°C for 8 hours to obtain a tan precipitate C; finally, the tan precipitate C was filtered, washed with deionized water, and heated at 110°C drying and grinding under conditions to obtain zinc oxide nanorods with manganese oxide surface modification. The manganese oxide nanoparticles covered on the surface of the zinc ...
Embodiment approach 2
[0025] First prepare a mixed aqueous solution of zinc acetate and manganese acetate with a concentration of 0.5-1M, wherein the molar amount of manganese acetate dihydrate added is equivalent to 5% of the molar amount of zinc acetate dihydrate added; Add a stable dose of urea to the aqueous solution, then slowly add ethanol, and stir magnetically until the urea is completely dissolved to obtain a clear solution A; then add NaOH to the clear solution A to adjust the pH value of the system to 12 to obtain a brown sol system B; The brown sol system B was transferred to a polytetrafluoroethylene-lined hydrothermal kettle, and the hydrothermal reaction was carried out at 120°C for 20 hours to obtain a tan precipitate C; finally, the tan precipitate C was filtered, washed with deionized water, and heated at 120°C drying and grinding under conditions to obtain zinc oxide nanorods with manganese oxide surface modification.
