Embodiment 1
[0015] Soak the anodic alumina template with a pore size of 100nm in 5wt% phosphoric acid, remove the dense alumina barrier layer at the bottom, and obtain a double-pass porous alumina template; put the double-pass porous alumina template into the middle of the reactor, fix it, and place the reactor Separate into two parts to form a double-chamber reactor; add 0.1M Ti(OC 4 h 9 ) 4 and 0.01M silver nitrate solution; add 0.1M barium nitrate solution on the other side of the double-chamber reactor, then add 0.005M lanthanum nitrate solution, the pH value of the solutions on both sides is controlled at 3-6; Leave it for 4-10 hours; take out the template and dry it under the infrared lamp, raise the temperature in the muffle furnace to 750°C at a rate of 5°C per minute and keep it for 1 hour for annealing; use 2mol / L NaOH solution to remove the Lanthanum-doped barium titanate nanotube arrays were obtained after redundant alumina template.
Embodiment 2
[0017] Soak the anodic alumina template with a pore size of 100nm in 5wt% phosphoric acid, remove the dense alumina barrier layer at the bottom, and obtain a double-pass porous alumina template; put the double-pass porous alumina template into the middle of the reactor, fix it, and place the reactor Separate into two parts to form a double-chamber reactor; add 0.1M Ti(OC 4 h 9 ) 4 and 0.01M silver nitrate solution; add 0.1M barium nitrate solution on the other side of the double-chamber reactor, then add 0.005M cerium nitrate solution, the pH value of the solutions on both sides is controlled at 3-6; Set it aside for 4-10 hours; take out the template and dry it under an infrared lamp, then heat it in a muffle furnace at a rate of 5°C per minute to 750°C for 1 hour for annealing; use 2mol / L NaOH solution to remove the The redundant alumina template was used to obtain cerium-doped barium titanate nanotube arrays.
Embodiment 3
[0019] Soak the anodic alumina template with a pore size of 100nm in 5wt% phosphoric acid, remove the dense alumina barrier layer at the bottom, and obtain a double-pass porous alumina template; put the double-pass porous alumina template into the middle of the reactor, fix it, and place the reactor Separate into two parts to form a two-way reactor; add 0.1M Ti(OC 4 h 9 ) 4 and 0.01M silver nitrate solution; add 0.1M barium nitrate solution on the other side of the double-chamber reactor, add 0.005M praseodymium nitrate solution, the pH value of the solutions on both sides is controlled at 3-6; stand in the air 4-10 hours; after taking out the template, dry it under the infrared lamp, raise the temperature in the muffle furnace to 750°C at a rate of 5°C per minute and keep it for 1 hour for annealing; use 2mol / L NaOH solution to remove excess Praseodymium-doped barium titanate nanotube arrays were obtained after alumina template.
