[0025] Spindle CuS@CeO 2 Preparation of nanocomposites (specific process such as figure 1 shown):
[0026] Weigh 17mgCuCl 2 ·H 2 O was added to 100mL deionized water, stirred in a 50°C water bath for 30min, then 14uL of mercaptoacetic acid was added, and the reaction was continued for 30min. The thioacetamide was added into the reaction system and reacted for 4 hours to obtain the copper sulfide reaction stock solution.
[0027] 500mgPAH and 217mgCe(NO 3 ) 3 ·6H 2 After O was added to the reaction system and stirred for 30 min, 0.5 mL NaOH (0.1 M) solution was prepared and poured into the reaction system. After reacting in a water bath at 50 °C for 12 hours, the spindle-shaped CuS@CeO was collected by centrifugation. 2 nanocomposites.
[0028] Spindle-shaped CuS@CeO prepared in the above examples 2 Nanocomposite materials through transmission electron microscopy figure 2 As shown, it can be clearly observed that the nanomaterials present a shuttle-shaped structure, ...
