Embodiment 1
[0040] In the first step, put 0.20g of 4.5 hydrated indium nitrate, 0.17g of trimesic acid, 1.00g of water and 4.00g of N,N-dimethylformamide in a beaker and mix them for 1 hour, then add 0.01 g of the ordered mesoporous carbon material CMK-3, and ultrasonically for 1 hour to mix the ordered mesoporous carbon material CMK-3 with the above mixture evenly.
[0041] In the second step, the mixed solution of the first step was put into a 25ml reaction kettle, subjected to hydrothermal reaction at a temperature of 120° C. for 5 days, and then naturally cooled to room temperature.
[0042] In the third step, the solid obtained in the second step is suction-filtered, washed successively with appropriate amount of distilled water and 95% ethanol, and dried overnight at 60° C. to obtain a composite material of indium-based organic framework compound CPM-5 and CMK-3.
[0043] In the fourth step, the composite material obtained in the third step is placed in a tube furnace, and in an atm...
