Embodiment 1
[0022] 3 grams of glucose, 3 grams of melamine, 3 grams of cobalt chloride and 5 milliliters of distilled water were mixed and ground into a uniform mixture, and the above mixture was dried at 80 degrees Celsius for 12 hours to obtain a pink solid; after the above pink solid was ground into a powder Transfer to the high-temperature tube furnace, heat up to 700 degrees Celsius in flowing nitrogen, and maintain 700 degrees Celsius for 4 hours to obtain a black solid; the above-mentioned black solid is cooled to room temperature, transferred to a glass beaker, and 50 milliliters of HCl is added with a content of 10 % (mass percent) hydrochloric acid solution, stirred and dissolved for 6 hours; after the above-mentioned solid matter washed with hydrochloric acid was suction-filtered with a microporous membrane, washed to neutrality with 2000 milliliters of distilled water, and then rinsed with 50 milliliters of acetone, The obtained solid matter was vacuum-dried at 50° C. for 10 ho...
Embodiment 2
[0024] 3 grams of glucose, 3 grams of melamine, 3 grams of cobalt chloride and 5 milliliters of distilled water were mixed and ground into a uniform mixture, and the above mixture was dried at 80 degrees Celsius for 12 hours to obtain a pink solid; after the above pink solid was ground into a powder Transfer to the high-temperature tube furnace, heat up to 750 degrees Celsius in flowing nitrogen, and maintain 750 degrees Celsius for 4 hours to obtain a black solid; the above-mentioned black solid substance is cooled to room temperature, transferred to a glass beaker, and 50 milliliters of HCl is added with a content of 10 % (mass percent) hydrochloric acid solution, stirred and dissolved for 6 hours; after the above-mentioned solid matter washed with hydrochloric acid was suction-filtered with a microporous membrane, washed to neutrality with 2000 milliliters of distilled water, and then rinsed with 50 milliliters of acetone, The obtained solid matter was vacuum-dried at 50° C....
