Octahedral anatase particles (OAP) with eight exposed and thermodynamically most stable (101) facets were prepared by an ultrasonication-hydrothermal (US-HT) reaction from potassium titanate nanowires (TNW). The precursor (TNW) and the product (OAP) of US-HT reaction were modified with nanoparticles of noble metals (Au. Ag or Pt) by photodeposition. Samples were characterized by X-ray... https://parisnaturalfoodes.shop/product-category/b12-drops-1000mcg/
