| Application: | Tantalum(V) fluoride can be used: • As a precursor for atomic layer deposition of thin films on the cathode materials of Li-ion batteries. • As a dopant to enhance the photochemical activity of hematite by improving charge carrier mobility and reducing recombination of photogenerated holes and electrons. • To enhance the photocurrent stability and photoluminescence of WO3 films (used as photoelectrode for photolysis of water). • As a catalyst for N-alkylation of arylamines with benzylalcohols. |
| General description: | Tantalum(V) fluoride is a volatile inorganiccompound widely used as a precursor for atomic layer deposition, to producemetal fluoride thin films and as a catalyst in various organic transformations. |
