Embodiment 1
[0022] Embodiment 1. Preparation of porous ruthenium sulfide nanospheres
[0023] In a 100ml round bottom flask, add 50ml dimethylformamide solvent, add 0.04g anhydrous ruthenium trichloride and 0.06g thiourea to the solvent, the ratio of the amount of substances of anhydrous ruthenium trichloride and thiourea is about The ratio is 1:4, the concentration of ruthenium trichloride is 4 mmol / L, and it is dissolved after mixing. The flask was placed in a microwave oven (the microwave oven was modified, the flask was connected with a reflux device, the same below), and heated to reflux for 15 minutes under microwave radiation with a power of 280W and a frequency of 2.45G (the same below). After the reaction, a gray-black precipitate was formed. After cooling to room temperature, centrifuge (9000 rpm, 5 min), wash the precipitate with ethanol and acetone in sequence, and then place the obtained precipitate at room temperature and air dry naturally. The product obtained was gray-bl...
Embodiment 2
[0024] Embodiment 2. Preparation of porous ruthenium sulfide nanospheres
[0025] Add 50ml of dimethylformamide solvent into a 100ml round bottom flask, add 0.04g of anhydrous ruthenium trichloride and 0.06g of thiourea into the solvent, mix and dissolve. The solution was placed under microwave radiation for 25 minutes under dielectric heating and reflux, and the other preparation conditions were the same as in Example 1. Similarly, 0.008 g of a product similar in size and form to Example 1 was obtained.
Embodiment 3
[0026] Embodiment 3. Preparation of porous ruthenium sulfide nanospheres
[0027]In a 100ml round bottom flask, add 50ml of dimethylformamide solvent, add 0.02g of anhydrous ruthenium trichloride and 0.03g of thiourea to the solvent, that is, the ratio of the amount of anhydrous ruthenium trichloride and thiourea is about The ratio is 1:4, the concentration of ruthenium trichloride is 2mmol / L, and it is dissolved after mixing. The solution was placed under microwave radiation and dielectrically heated to reflux for 15 minutes, and the other preparation conditions were the same as in Example 1. The obtained amorphous nanospheres have a diameter of 140-200nm (see accompanying drawing 6), and the porous ruthenium sulfide nanospheres obtained after calcining have a diameter of about 100nm (see accompanying drawing 7) and weigh 0.004 grams.
