General description
Aluminum-tri-sec-butoxide is a metal organic chemical vapor deposition precursor and a chelating agent. It is widely used as a sol-gel precursor to deposit alumina thin films by atomic layer deposition method.
Application
Aluminum-tri-sec-butoxide can be used as a precursor :
- To prepare Al2O3-based quasi-solid electrolyte for Li metal anodes. This ensures long cycle lifetime and high constant current density.
- To synthesize nanospinel MgAl2O4 powder by a sol–gel method at low-temperature processing.
- To fabricate transparent superhydrophobic aluminum oxide thin films to prevent soiling of solar panels.
- To synthesize mesoporous alumina with large surface area to fabricate a functional interlayer for separator coating in a Li–S battery. It helps to suppress the shuttle effect and enhances cyclic stability andrateperformance.
Features and Benefits
- Suitable for thin film deposition
- Solubility in various solvents allows for the facile preparation of solution-based precursors
- High thermal stability
- Facilitates the anchoring of catalytic metal nanoparticles onto substrates
Has been utilized in making high-surface-area alumina using 2,4-pentanedione (Aldrich product P775-4) as a chelating agent.
