Embodiment 1
[0047] HoPO 4 2H 2 Preparation of O nanomaterials.
[0048] NaOH (0.6 g) was added to a solution of ethanol (10 mL) oleic acid (10 mL), and the mixture was stirred. Add NaHPO to the reaction mixture 4 2H 2 O (5mL, 2molL -1 ) and Ho(NO 3 ) 3 (5mL, 2molL -1 ), some amorphous precipitates appeared immediately. After stirring for a while, the mixture was transferred to a reaction kettle (50 mL), and then ethanol (15 mL) was added. The autoclave was sealed and the reaction was heated to 190 °C for 16 hours. The reaction was then cooled to room temperature and the final product spontaneously separated at the bottom of the autoclave. Finally, it was dried overnight in an oven at 60° C. to obtain the final product for future use.
[0049] Prepared HoPO 4 2H 2 TEM of O nanomaterials such as figure 2 As shown in A, the XRD analysis is as follows figure 1 shown. Depend on figure 2 A can be obtained, the length of the hexagonal plane is between 50-100nm. image 3 for H...
Embodiment 2
[0051] HoPO 4 2H 2 Preparation of O nanomaterials.
[0052] NaOH (0.6 g) was added to a solution of ethanol (9.5 mL) oleic acid (9.5 mL), and the mixture was stirred. Add NaHPO to the reaction mixture 4 2H 2 O (5mL, 2molL -1 ) and Ho(NO 3 ) 3 (5mL, 2molL -1 ), some amorphous precipitates appeared immediately. After stirring for a while, the mixture was transferred to a reaction kettle (50 mL), and then ethanol (15 mL) was added. The autoclave was sealed and the reaction was heated to 185°C for 17 hours. The reaction was then cooled to room temperature and the final product spontaneously separated at the bottom of the autoclave. Finally, it was dried overnight in an oven at 55° C. to obtain the final product for future use.
Embodiment 3
[0054] HoPO 4 2H 2 Preparation of O nanomaterials.
[0055] NaOH (0.6 g) was added to a solution of ethanol (10.5 mL) oleic acid (10.5 mL), and the mixture was stirred. Add NaHPO to the reaction mixture 4 2H 2 O (5mL, 2molL -1 ) and Ho(NO 3 ) 3 (5mL, 2molL -1 ), some amorphous precipitates appeared immediately. After stirring for a while, the mixture was transferred to a reaction kettle (50 mL), and then ethanol (15 mL) was added. The autoclave was sealed and the reaction was heated to 195°C for 15 hours. The reaction was then cooled to room temperature and the final product spontaneously separated at the bottom of the autoclave. Finally, it was dried overnight in an oven at 65° C. to obtain the final product for future use.
