Lanthanum hydroxide nanoparticles

Technical Parameters

Main Features

Anhui Zhonghang Nano produces nano lanthanum hydroxide using special processes and nano-membrane purification technology. The product offers advantages such as high whiteness, pure crystal phase, low magnetic metal impurities (≤50ppb), low moisture content, and stable chemical properties. Nano lanthanum hydroxide has a large specific surface area and a unique electronic structure, enabling it to form lanthanum complexes with other elements, thereby reacting more thoroughly with reactants and significantly enhancing its catalytic activity. When exposed to external light, the energy band structure of La(OH)₃ semiconductor particles allows them to absorb photon energy hv. When this energy is greater than or equal to the bandgap, valence electrons in the La(OH)₃ semiconductor are excited and transition from the valence band to the conduction band, forming electron-hole pairs within La(OH)₃. Under an electric field, these photogenerated electrons and holes separate via diffusion and migrate to different positions on the La(OH)₃ particles. These excited-state electrons and holes can undergo redox reactions with electron donors and acceptors adsorbed on the semiconductor particle surface, thereby enabling the oxidation of organic pollutants.
