| titleOfInvention | Method for hydrothermally preparing nitrogen-doped sodium tantalate photochemical catalyst powder |
| abstract | The invention provides a method for hydrothermally preparing nitrogen-doped sodium tantalate photochemical catalyst powder. The method comprises the following steps: taking tantalum oxide (Ta2O5), sodium hydroxide (NaOH), sodium azide (NaN3) and hydrazine hydrate (N2H4.H2O) as raw materials; adding water and preparing into a solution, and then fully stirring till Ta2O5 and NaOH are completely dissolved, thereby forming a precursor solution; placing the precursor solution into a reaction kettle; reacting for 12 hours at 160 DEG C according to a hydrothermal method; cooling after finishing the reaction; taking out the sediment from the reaction kettle; and washing the sediment to be neutral with deionized water and absolute ethyl alcohol, and then drying at a constant temperature of 80 DEG C, thereby obtaining the powder. A rhodamine B is taken as a degrading agent in photocatalytic reaction of NaTaO3-N powder, and after 150 minutes, the degrading rate can reach above 90%. According to the method provided by the invention, the reaction temperature is low, the NaTaO3-N powder can be prepared at 160 DEG C, and the photocatalytic activity under the irradiation of ultraviolet lights is better. |
