Application
- An organic additive in the synthesis of metal nanoparticles to control the size and morphology of nanostructure.
- A carbon source to prepare acidophilic highly fluorescent carbon dots (CDs) via the one-pot hydrothermal method.
- A dispersion stabilizer to synthesize amorphous Fe2O3 nanoparticles by microwave irradiation method. During the synthesis, PEG-2000 inhibits nonhomogeneous precipitation to obtain homogeneous precipitation of the metal nanoparticles.
