General description

Gallium(III) acetylacetonate is a sol-gel precursor used to synthesize high-purity GaN nano-wires, nano-needles, and gallium oxide thin films, which are relevant to applications in batteries, fuel cells, and solar cells.

Application

Gallium(III) acetylacetonate can be used:
  • As a precursor to synthesize nanocrystalline gallium oxide spinels via solvothermal process for various applications like photocatalysis, battery cathode materials and electrocatalysis.
  • To fabricate LiGa alloy layer on Li metal anode from in-situ electroreduction. It suppresses the anode dendrite formation in lithium-sulfur batteries.
  • To prepare highly efficient gallium-platinum (GaPt3) nanoparticles hot-solvent synthesis which act as electrocatalysts for hydrogen evolution reaction.
  • To synthesize γ-Ga2O3 nanocrystals for fabricating electron-transporting layer for perovskite solar cells. It forms effective interfacial connections with the perovskite top layer, enhancing the efficiency of charge transport.
