Embodiment 1
[0028] Weigh 1.3 g RuNO (NO 3 ) 3 , 17.1 g ZrO(NO 3 ) 2 2H 2 O was dissolved in 156 mL deionized water, transferred to a 200 mL hydrothermal kettle, heated at 170 °C for 6 h, and naturally cooled to room temperature to obtain a khaki slurry; the slurry was taken out and washed with 10 wt.% NaOH solution As a precipitating agent, precipitation was carried out at 60 °C, and the pH at the end of the precipitation was controlled to be 9, and it was aged for 4 h; the obtained precipitate was centrifuged and washed with deionized water until it was neutral; after the precipitate was vacuum-dried at 80 °C for 12 h, Calcined at 200 °C for 6 h under hydrogen atmosphere.
Embodiment 2
[0030] Weigh 0.48 g KRuO 4 , 17.1 g ZrO(NO 3 ) 2 2H 2 O was dissolved in 156 mL of 10 vol.% alcohol solution, transferred to a 200 mL hydrothermal kettle, heated at 130 °C for 18 h, and naturally cooled to room temperature to obtain a khaki-yellow slurry; the slurry was taken out and washed with 10 wt.% KOH solution was used as a precipitating agent, and the precipitation was carried out at 70 °C. The pH of the precipitation termination was controlled to be 13, and the precipitation was left to age for 12 h; the obtained precipitate was washed with deionized water to neutrality; After drying for 12 h, they were calcined at 450 °C for 4 h in a hydrogen atmosphere.
Embodiment 3
[0032] Weigh 2.14 g RuCl 3 ·3H 2 O, 20.6 g ZrOCl 2 ·8H 2 O was dissolved in 150 mL of deionized water, transferred to a hydrothermal kettle with a capacity of 200 mL, heated at 150 °C for 12 h, and naturally cooled to room temperature to obtain a khaki-yellow slurry; the slurry was taken out and washed with 10 wt.% NaOH solution As a precipitating agent, precipitate at 80 °C, control the pH of the end of the precipitation to 10, let stand and age for 12 h, add 1 mL of 30 wt.% H 2 o 2 solution; the resulting precipitate was centrifuged and washed with a mixture of acetone and deionized water (volume ratio 1:5) until AgNO 3 The solution was detected to be free of chloride ions; the precipitate was vacuum-dried at 80 °C for 12 h, and then calcined at 300 °C for 4 h in a hydrogen atmosphere.
