Application

Polyethylene glycol 20000 (PEG-20000) can be used as a pore-expanding agent to prepare mesoporous La₂O₃ catalyst via hydrothermal process. The effect of PEG 20000 on La₂O₃ catalyst particles, results in increased alkalinity, crystallinity, specific surface area, and dispersion. These modifications of the catalyst improve the catalytic performance in the transesterification of dimethyl carbonate with glycerol. It can also be used as: A surfactant in the synthesis of nanomaterials by various methods to control the size and morphology of nanostructure. A support to prepare zero-valent iron-PEG nanocomposite material (Fe/PEG) applicable in the removal of Pb(II) from aqueous solutions.
