Embodiment 1

[0115] Example 1: NixP@g-C 3 N 4 Catalyst and NixP@g-C 3 N 4 / NF electrode preparation and characterization

[0116] New NixP@g-C 3 N 4 The preparation steps of / NF electrode are as follows:

[0117] (1) Firing g-C 3 N 4

[0118] First, weigh a certain amount of thiourea and place it in a crucible, then place the crucible in a muffle furnace and heat it up to 550°C (heating rate 2°C / min) and keep it for 2h. Grind the yellow solid in a porcelain mortar for a certain period of time, then pour it back into a crucible, place it in a muffle furnace and heat it up to 500°C (heating rate 2°C / min) and keep it there for 2 hours, then take out the crucible after cooling down to room temperature, and grind the yellow-white powder A certain time, this is g-C 3 N 4 .

[0119] (2) Pretreatment of nickel foam

[0120] 1×2cm nickel foam was ultrasonically pretreated in 3mol / L hydrochloric acid solution, acetone, deionized water and ethanol solution for 15 minutes, washed three ti...

Embodiment 2

[0129] Example 2: NixP@g-C 3 N 4 Electrochemical performance test comparison between / NF electrode and other electrodes

[0130] (1) Preparation of other electrodes:

[0131] Get g-C among the embodiment 1 3 N 4 Put 10mg into a 250mL beaker, add 10mg magnesium nitrate hexahydrate and 100mL isopropanol solution, and sonicate for 3h. The above solution is used as the electrophoresis liquid, nickel foam is used as the cathode, and the platinum electrode is used as the anode in the electrophoresis instrument for 10 minutes, and the prepared electrode is taken out and rinsed with deionized water, and dried, that is, g-C 3 N 4 / NF electrode.

[0132] In order to further compare catalyst performance, 20wt% commercial Pt / C catalyst is dispersed in the solution of ethanol and water, the volume ratio is 4:1, then add 40 microliters of Nafion solution, supergene 20min, then the above-mentioned mixed homogeneous The phase catalyst was loaded on the nickel foam, and finally, the sam...

Abstract

The invention discloses a phosphorus-containing compound, and a preparation method and an application thereof, and belongs to the fields of material science and technology and chemistry. The phosphorus-containing compound is prepared from cheap raw materials through the simple method; the method is essentially characterized in that the compound is prepared from metal ions and a phosphorus source under the illumination condition of a photoactive material; and the temperature in the prior art is more than 100 DEG C, and the method in the invention is a normal temperature synthesis process, so the obtained compound has a weak crystallization degree. The phosphorus-containing compound has a high photocatalytic activity as a conventional catalyst and a photocatalytic reaction cocatalyst, and achieves a high hydrogen production rate for a photocatalytic hydrogen production reaction. The method and the phosphorus-containing compound can be used for producing an electrode and producing a battery, so the production cost of the electrode and the battery is reduced, the preparation method is simplified, and the obtained electrode is a non-noble metal catalyst, and has the advantages of low cost, low overpotential, high stability and certain industrial application values.

Description

technical field [0001] The invention relates to a phosphorus-containing compound and its preparation and application, belonging to the fields of material science and technology and chemistry. Background technique [0002] Global environmental pollution and energy crisis are becoming more and more serious, and the development of new sustainable energy has attracted the attention of countries all over the world. Among them, hydrogen is considered to be the most ideal energy source because of its abundant sources, high combustion value, and clean and pollution-free combustion products. Hydrogen production by splitting water is one of the important methods to achieve large-scale production of hydrogen. The use of solar energy to decompose water to produce hydrogen and convert solar energy into chemical energy stored in hydrogen energy provides a cheap and convenient way to obtain hydrogen. The development of cheap and efficient photocatalysts is the key to photocatalytic water ...
