Abstract
Tantalum vanadate (TaVO5) forms into nanostructures, particularly nanorods, which may range in length between 100 and 600 nm with a length:width ratio between 20:1 to 50:1, and, as a bulk material, have a bandgap of 1.5 to 3.00 eV. Such nanostructures may be prepared by the hydrothermal method.
Claims20
A method of preparing a TaVO5 nanorod, the method comprising:
- heating, at a temperature in a range of from 150 to 300° C., for a time period in a range of from 5 to 72 hours, a mixture comprising a metavanadate, an acid, and a soluble tantalum compound;
- forming TaVO5 nanorods having an average length-to-width ratio of at least 15:1,
- wherein the acid comprises at least one selected from the group consisting of formic acid, acetic acid, glycolic acid, propionic acid, butyric acid, citric acid, methanesulfonic acid, oxalic acid, malic acid, glutaric acid, maleic acid, fumaric acid, phenol, benzoic acid, salicylic acid, and tartaric acid, and/or
- wherein the acid and the metavanadate comprise H3VO4.
1 more element
A composition, comprising:
- a plurality of nanorods,
- wherein at least 75 wt. % of a total weight of the nanorods is TaVO5.
A nanorod, comprising:
- TaVO5 in at least 75 wt. % of total nanorod weight.
