Embodiment 1
[0026] 1) Disperse 2.5 g of glucose hydrothermally obtained at 180° C. in ethanol, stir first for 3 hours, and then ultrasonicate for 1 hour to make it uniformly dispersed.
[0027] 2) above-mentioned solution, under the action of magnetic stirring, add the solid powder of tin tetrachloride pentahydrate of 0.25g, magnetic stirring 6 hours, be denoted as solution A;
[0028] 3) The above solution A is kept in a state of stirring, and 0.40 g of thioacetamide is added therein, which is denoted as solution B;
[0029] 4) The other magnetic stirrer was adjusted to the heating state, and the temperature was raised to 55 degrees Celsius and maintained.
[0030] 5) Put solution B on a magnetic stirrer with a set temperature, and heat until the ethanol is basically evaporated to dryness, add 50 ml of ethanol, and heat for 20 min, which is recorded as solution C.
