Product Description

Product Description

Tantalum oxide generally refers to Tantalum pentoxide, also known as "tantalum anhydride, white diamond crystal".
Its chemical properties are stable, acid and alkali resistant, and it is not corroded by hydrogen chloride or chemicals when heated.
The corresponding insoluble tantalate can be obtained by eutectic with alkali metal hydroxide or carbonate, which can be washed and hydrolyzed to generate hydrated Tantalum pentoxide precipitation.
Tantalum oxide can be used as an intermediate for preparing metal tantalum, optical glass, electronic instruments and Tantalum carbide, as well as Lithium tantalate single crystal and special optical glass with high refraction and low dispersion, and as a catalyst in the chemical industry.

Product Applications

1) Prepare Tantalum pentoxide nanoparticles/Graphene composite photocatalyst, use Graphite oxide as the matrix, use commercial Tantalum pentoxide to prepare the precursor of the catalyst, adjust the precursor of Tantalum pentoxide through other reagents, and assist ultrasonic method to realize the growth of Tantalum pentoxide nanoparticles on the surface of Graphene, and obtain Tantalum pentoxide nanoparticles/Graphene composite photocatalyst. The prepared Tantalum pentoxide nanoparticles/Graphene composite photocatalyst, due to the electron reception of Graphene and the UV photocatalysis of nano Tantalum pentoxide, has broad application prospects in the photocatalytic decomposition of organic pollutants, water photolysis and hydrogen production.
2) Perovskite solar cell with Tantalum pentoxide as electron transport layer: Tantalum(V) chloride was dissolved in alcohol to prepare precursor solution with concentration of 0.01mol/L-0.06mol/L; The precursor solution is coated on the transparent conductive substrate, and then annealed at 500-600 ºC to form a layer of Tantalum pentoxide film with a thickness of 5nm-60nm on the surface of the conductive substrate; The perovskite precursor solution is coated on the surface of Tantalum pentoxide film, and then annealed at 100-110 ºC to form a perovskite absorption layer with a thickness of 400nm-500nm on the surface of Tantalum pentoxide film; The surface of the perovskite absorbing layer is sequentially modified with a hole transport layer and a metal electrode to obtain a perovskite solar cell. The method of the invention has simple process and low cost, and uses Tantalum pentoxide film as an electron transmission layer, which can accelerate the migration ability of electrons and improve the utilization ratio of light.
3) High density Tantalum pentoxide film material is prepared, and Tantalum pentoxide powder is hot pressed in a vacuum graphite furnace; This includes the following steps: (1) Use a mechanical pump to vacuum to 1 × 103~5 × 103Pa, then turn on the diffusion pump to vacuum to 1 × 10-3-5 × 10-3Pa; Then fill with argon gas for protection, and raise the temperature to 1300~1600 ºC; (2) Maintain the temperature at 1300~1600 ºC and pressurize it to 18~25MPa for a holding time of 25~35min. During the holding period, protect the sintering environment with inert gas argon gas to maintain a pressure of 1 × 103~1 × Between 104Pa; (3) High density Tantalum pentoxide film material is obtained by cooling to room temperature at a cooling rate of 3~7 ºC/min. The invention realizes further densification of materials by high-temperature pressure, simplifies the traditional production process of Tantalum pentoxide, and can prepare coating materials with higher density and purity by high-temperature pressure.
4) A shuttle Tantalum pentoxide photocatalyst is prepared, which comprises: dispersing metal tantalum powder in Ultrapure water and placing it in the first lining, uniformly mixing hydrofluoric acid and hydrogen peroxide solution and placing it in the second lining for hydrothermal reaction; After the reaction is completed, the suspension in the first lining is naturally cooled, centrifuged, cleaned, and dried to obtain. The invention has simple preparation method, good repeatability, high crystallinity, controllable morphology and high photocatalytic efficiency, and has broad application prospects in water photolysis, hydrogen production and water treatment.
