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 ¡æ 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 ¡æ.

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 ¡æ 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 ¡æ drying 10h, and got  C nanoparticles.
