Embodiment 1
[0025] (1) Mix distilled water and activated carbon at a ratio of 5 mL / g, boil for 1 hour, wash repeatedly with distilled water until the upper liquid is clear, take out the activated carbon and dry it; mix the dried activated carbon with 25% HNO 3 After the solution was mixed at a ratio of 5mL / g, it was heated to boiling and kept stirring until the HNO 3 The solution was completely volatilized, and the acidified activated carbon was washed with distilled water until the filtrate pH=7, and the obtained activated carbon was dried at 100°C;
[0026] (2) Add 1g RuCl 3 ·3H 2 O and 15 mL of absolute ethanol were placed in a three-necked flask and heated at 70 °C until RuCl 3 ·3H 2 O is completely dissolved, slowly drop 1,5-cyclooctadiene into rhodium trichloride ethanol solution, and continue to heat and reflux at 70°C for 4 hours to generate an orange crystal product, which is washed with absolute ethanol, and the washed crystal is put into Into drying oven, wherein the mol ra...
Embodiment 2
[0030] (1) Mix activated carbon and distilled water at a ratio of 3mL / g and boil for 1.5h, wash repeatedly with distilled water until the upper liquid is clear and dry; mix the dried activated carbon with 30% HNO 3 After the solution was mixed at a ratio of 4mL / g, it was heated to boiling and kept stirring until the HNO 3 The solution was completely volatilized, and the acidified activated carbon was washed with distilled water until the filtrate pH=7, and the obtained activated carbon was dried at 100°C;
[0031] (2) Add 1g RuCl 3 ·3H2 O and 18 mL of absolute ethanol were placed in a three-necked flask, and heated to RuCl at 80°C 3 ·3H 2 O is completely dissolved, slowly drop 1,5-cyclooctadiene into rhodium trichloride ethanol solution, continue to heat and reflux at 80°C for 2 hours, and produce an orange crystal product, wash the obtained product with absolute ethanol, and put the filtered crystal into Into drying oven, wherein the mol ratio of 1,5-cyclooctadiene and rho...
Embodiment 3
[0035] (1) Mix activated carbon and distilled water at a ratio of 4 mL / g and boil for 2 hours, then wash repeatedly with distilled water until the upper liquid is clear, then take out the activated carbon and dry it; mix the dried activated carbon with 8% HNO 3 After the solution was mixed at a ratio of 3mL / g, it was heated to boiling and kept stirring until the HNO 3 The solution was completely volatilized, and the acidified activated carbon was washed with distilled water until the filtrate pH=7, and the obtained activated carbon was dried at 105°C;
[0036] (2) Add 1g RuCl 3 ·3H 2 O and 20 mL of absolute ethanol were placed in a three-necked flask, and heated at 90 °C to RuCl 3 ·3H 2 O is completely dissolved, slowly drop 1,5-cyclooctadiene into the ethanol solution of rhodium trichloride, continue to heat and reflux at 60°C for 3 hours, and produce an orange crystal product, wash the obtained product with absolute ethanol, and put the filtered crystal into Into drying ...
