| 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 |
| Features and Benefits: | Has been utilized in making high-surface-area alumina using 2,4-pentanedione (Aldrich product P775-4) as a chelating agent. |
| 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. |
