Abstract

The invention discloses a Ce-doped sodium nickel phosphate photocatalytic material, wherein the chemical formula of the substrate material of the Ce-doped sodium nickel phosphate photocatalytic material is Na4Ni3P4O15, and the surface of the substrate material is doped with a Ce salt. The invention also discloses a preparation method of the Ce-doped sodium nickel phosphate photocatalytic material.According to the method for preparing the cerium salt doped sodium nickel phosphate photocatalytic material by selecting hydrated carbon nickel sodium, phosphoric acid and a cerium salt, the introduction of other impurities is effectively avoided, the purity of the synthesized sodium nickel phosphate is improved, and the photocatalytic activity is also improved; The Ce salt is doped on the surface of sodium nickel phosphate, so that the corresponding range of sodium nickel phosphate in ultraviolet light and visible light regions is effectively widened, the structure is affected to form lattice defect, and photo-induced electron pair separation is facilitated; and the method is an environmentally friendly reaction, does not need a complex process, is simple to control and low in cost, is easy for batch production, and can quickly realize industrialization.

Description

technical field [0001] The invention belongs to the technical field of preparation of sodium nickel phosphate photocatalytic materials, and in particular relates to a Ce-doped sodium nickel phosphate photocatalytic material and a preparation method thereof. Background technique [0002] Photocatalysis technology is a basic nanotechnology born in the 1970s. In mainland China, we use the popular term photocatalyst to refer to photocatalysts. A typical natural photocatalyst is our common chlorophyll, which promotes the synthesis of carbon dioxide and hydration in the air into a mixture of oxygen and carbohydrates in the photosynthesis of plants. Photocatalysts can be used in many cutting-edge fields such as environmental purification, self-cleaning materials, advanced new energy, cancer medical treatment, and high-efficiency antibacterial. [0003] There are many materials that can be used as photocatalysis in the world, including titanium dioxide (TiO 2 ), zinc oxide (ZnO), ...
