specific Embodiment approach 1
[0018] Specific embodiment one: the preparation method of the artificial nanotube of the present embodiment is carried out according to the following steps:
[0019] 1. Preparation of metal catalytic particles;
[0020] 2. Using porous alumina sheets, polycarbonate (PC) or porous silicon sheets as templates, assemble polyelectrolyte layers into the holes of the template to obtain the skeleton of nanotubes;
[0021] 3. Assembling the metal catalyst particles prepared in step 1 onto the skeleton of nanotubes obtained in step 2;
[0022] 4. Dissolving and removing the template treated in step 3 with a template solvent to obtain artificial nanotubes.
[0023] This embodiment uses platinum or silver nanoparticles that catalyze hydrogen peroxide to decompose oxygen, templates for preparing nanotubes, artificial or natural polyelectrolytes for preparing nanotubes as basic materials, and use layer-by-layer assembly methods to combine polyelectrolyte nanotubes with The metal particle...
specific Embodiment approach 2
[0024] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the metal catalytic particles in step 1 are platinum particles with a particle size of 3nm to 100nm, silver particles with a particle size of 3nm to 100nm, or platinum or silver particles as the core Microparticles coated with citric acid or polydimethyldiallylammonium chloride with a particle size of 3nm to 100nm. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0025] Embodiment 3: This embodiment differs from Embodiment 1 and Embodiment 2 in that the pore diameter of the porous alumina sheet is 200-400 nm. Others are the same as those in the first and second specific embodiments.
[0026] The porous alumina sheet of this embodiment is a commercially available product.
