EG is a cross linker, stabilizer of metal ion precursors, enhance interaction via hydrogen bonding or coordination and allows formation of intermolecular network

I used it as DES..

Ethylene glycol acts as a complexing agent in the sol-gel method, which is a wet-chemical technique used for synthesizing metal oxide nanoparticles. It helps to control the hydrolysis and condensation reactions of metal precursors, leading to the formation of a gel network.

Ethylene glycol can also influence the porosity and catalytic performance of the resulting metal oxides.
