specific Embodiment approach 1
[0029] Specific implementation mode one: the preparation method of the egg yolk type Fenton microreactor loaded with noble metal nanoparticles on the inner surface of the present implementation mode comprises the following steps:
[0030] 1. Disperse the magnetic nanoparticles into water, then add ethyl orthosilicate to a final concentration of 1mg / mL-30mg / mL, stir for 2-3min, then add ammonia water to a final concentration of 0.01mg / mL-1mg / mL, React for 6-12h to obtain product A;
[0031] 2. Add the product A into the noble metal salt solution, wherein the final concentration of the noble metal salt is 0.1mg / mL~10mg / mL, after stirring for 10min~30min, add the reducing agent until the final concentration is 1mg / mL~50mg / mL, and react for 10min ~60min, product B was obtained;
[0032] 3. Disperse the product B in the conductive polymer monomer, wherein the final concentration of the conductive polymer monomer is 10 mg / mL-100 mg / mL, and add an initiator until the final concentra...
specific Embodiment approach 2
[0034] Embodiment 2: This embodiment differs from Embodiment 1 in that the magnetic nanoparticles described in step 1 are ferric oxide, ferric oxide or iron oxyhydroxide. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0035] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: in step 1, tetraethyl orthosilicate is added to a final concentration of 5 mg / mL-25 mg / mL. Others are the same as in the first or second embodiment.
