Uses Trioctylphosphine oxide (TOPO) is most commonly used as the solvent due to its high boiling point and chemical stability, and its ability to prevent particle aggregation via coordination to the NP surface. trioctylphosphine oxide is a frequently used surfactant, starts to decompose at around 425°C. The industrial applications of trioctylphosphine oxide, make use of its complexing powers with metals and with hydrogen donor organic compounds. Commercial uses as a solvent extraction reagent are in the recovery of uranium from wet process phosphoric acid and in the recovery of byproduct acetic acid and furfural generated during sulphite wood pulping. TOPO is a widely used chemical compound in nanocrystal synthesis, for the removal of heavy metals, and the removal of toxins in waste water. TOPO is often used as a ligand stabilizer for colloids in traditional thermal decomposition synthetic techniques. trioctylphosphine oxide became a nearly irreplaceable solvent (mp 51-52°C) for high-temperature preparation of various type of nanocomposites. TOPO has a very high boiling point (411°C) which is an important prerequisite for the homogeneous nucleation and good crystallinity of the nanoparticles. Tri-n-octylphosphine oxide is a solvent used in the extraction of metals, especially uranium, zirconium and hafnium. It is also used as an auxiliary reagent in the solvent extraction of metals. It is also used to extract hydrogen bonding organic compounds. Further, it is useful as a capping ligand for the production of quantum dots, such as those consisting of cadmium selenide.
