Photocatalytic material for efficient and selective reduction and removal of nitrate nitrogen in water, and preparation method thereof |
| abstract |
Disclosed is a method for preparing a photocatalytic material for efficient and selective reduction and removal of nitrate nitrogen in water, comprising the following steps: mixing gadolinium nitrate nonahydrate, chromium trioxide and urea and placing the mixture into an alumina crucible, then adding absolute ethanol and stirring the mixture evenly; placing the crucible into a muffle furnace to conduct calcination; grinding the solid obtained after calcination in a mortar to obtain GdCrO3 powder; adding the obtained GdCrO3 powder to a palladium chloride solution, then adding methanoic acid and performing UV light irradiation, whereby palladium chloride is reduced to a palladium simple substance, which is deposited onto the surface of GdCrO3, affording Pd/GdCrO3; and finally, performing centrifuging, washing and drying. |
