| 称取Xg A (按 A 的物质的量为 B 的1.2倍)于研钵中研细后，放入恒温干燥箱中110℃干燥0.5h除去结晶水，得白色粉未，冷却后加入1mL无水乙醇润湿，拌匀后，移取YmL B 加入，再研磨30min，得白色糊状物，放置24h，变为白色粉未。研细后，转移至坩埚中，在一定温度下煅烧Mh(将炉子加热到所需温度后再放入样品)，冷却后，样品用3mol/L醋酸20mL浸泡5h，然后样品用蒸馏水超声洗涤3次，再用无水乙醇和蒸馏水超声洗涤2次（最后一次用乙醇洗），放入干燥箱中100℃干燥10h，得C纳米粒子。 |

| Weigh Xg A (by A quantity of material B, 1.2 times) in a mortar in the research into smaller, placed in drying oven temperature 110 ℃ drying 0.5h to remove crystal water, was a white powder, cooling water, after adding 1mL ethanol wetting, mix well, the shift to take YmL B to join, and then grinding 30min, was a white paste, placing 24h, into a white powder. After detailed research, transfer to the crucible, to a certain temperature calcination Mh (the furnace heated to the desired temperature and then placed in the sample), after cooling, the sample with 3mol / L acetic acid 20mL soaking 5h, and then the sample with distilled water ultrasonic washed three times, then anhydrous ethanol and distilled water and ultrasonic washing two times (the last time that we use ethanol wash), placed in drying oven 100 ℃ drying 10h, and got C nanoparticles. |

| After weighing Xg A (by A quantity of material B, 1.2 times) in a mortar and milling it into smaller, it was placed in a drying oven at a temperature of 110 ℃ drying 0.5h to remove crystal water, and a white powder was gained.Then after cooling 1mL ethanol was added to wetting,and it was mixed well.A white paste was got when Yml B was added in and grinded for 30min, placing 24h, into a white powder. After a fine grinding , it was transfered to the crucible, through a Mh calcination at a certain temperature (the furnace heated to the desired temperature and then placed in the sample), after cooling, C nanoparticles will be obtained after the treatment of the soak for 5h in 20ml 3mol / L acetic acid , wash three times by distilled water ultrasonic , then wash two times by anhydrous ethanol and distilled water ultrasonic (the last time ethanol was used ), drying 10h in drying oven at 100 ℃. |
