Embodiment 1

[0022] Dissolve 1 mmol of iron-nickel nitrate in 5 ml of N,N-dimethylformamide (solution A), and dissolve 1 mmol of 2-carboxyethylphosphonic acid in 10 ml of N,N-dimethylformamide (solution B). Add solution A to solution B dropwise under magnetic stirring. After reacting for 12 hours under solvothermal conditions at 140° C., the sample was washed by centrifugation and collected to obtain amorphous iron-nickel phosphonate.

[0023] The photocatalytic performance of the amorphous iron-nickel phosphonate prepared in Example 1 was measured in a closed gas circulation system, and the reaction system was kept at about 20° C. by circulating cooling water. With photocatalyst (the amorphous iron nickel phosphonate that embodiment 1 makes, nickel phosphate), [Ru(bpy) 3 ] Cl 2 ·6H 2 O and Na 2 S 2 o 8 Mix in borate buffer. A 300w xenon lamp was selected as the light source, and the reaction system was backfilled with argon several times to remove air before illumination. Determin...

Embodiment 2

[0026] Dissolve 2mmol of iron-nickel nitrate in 15ml N,N-dimethylformamide (solution A), dissolve 2mmol of 2-carboxyethylphosphonic acid in 15ml N,N-dimethylformamide (solution B), in Add solution A to solution B dropwise under magnetic stirring. After reacting for 24 hours under solvothermal conditions at 160° C., the sample was washed by centrifugation and collected to obtain amorphous iron-nickel phosphonate.

Embodiment 3

[0028] Dissolve 3mmol of iron-nickel nitrate in 25ml of N,N-dimethylformamide (solution A), and dissolve 4mmol of 2-carboxyethylphosphonic acid in 30ml of N,N-dimethylformamide (solution B). Add solution A to solution B dropwise under magnetic stirring. After reacting for 36 hours under solvothermal conditions at 200° C., the samples were washed by centrifugation and collected to obtain amorphous iron-nickel phosphonate.

Abstract

The invention discloses a preparation method of amorphous iron-nickel phosphonate with an efficient photocatalysis oxygen production property. The preparation method comprises the following steps: (1)respectively dissolving nickel nitrate and 2-carboxyethyl phosphonic acid by using N,N-dimethyl formamide so as to obtain a solution A and a solution B; and (2) enabling the solution A and the solution B to react under a heating condition, so as to obtain the amorphous iron-nickel phosphonate with the efficient photocatalysis oxygen production property. The invention further discloses the amorphous iron-nickel phosphonate prepared by using the method, and application of the amorphous iron-nickel phosphonate as a photocatalyst. By adopting the preparation method, an amorphous iron-nickel phosphonate catalyst can be prepared by changing reaction conditions, the process operation is simple, the repeatability is high, and laboratory and industrial requirements can be met. The amorphous iron-nickel phosphonate catalyst prepared by using the method has the efficient photocatalysis oxygen production property.

Description

technical field [0001] The invention relates to an amorphous iron-nickel phosphonate with high-efficiency photocatalytic oxygen production performance, a preparation method thereof, and an application as a photocatalyst, belonging to the technical field of material preparation. Background technique [0002] With the rapid development of global population and economy, coal, oil and other non-renewable energy sources are being exhausted, and the resulting environmental pollution is also threatening the earth on which human beings depend for survival. Solar energy is a widely distributed, abundant and clean renewable energy. In order to make better use of solar energy, various solar energy conversion and storage technologies have emerged as the times require. [0003] Since 1972, Fujishima and Honda first reported the use of TiO in sunlight 2 The photolysis of water with Pt electrodes successfully obtained hydrogen and oxygen, which opened the exploration of semiconductor pho...
