Description
Technical Field
The invention relates to a preparation method of a nickel-iron bimetal coordination polymer catalyst for water electrolysis, belonging to the technical field of catalytic materials.
Background
With the progress of science and technology, renewable energy represented by solar energy and wind energy is greatly developed, and the proportion of the renewable energy in the total amount of the global energy power generation and installation machine is increased continuously. However, since the emerging renewable energy sources have time period fluctuation in the power supply, a reliable energy storage method must be found to adjust the energy difference between the peak and the trough of the power generation. Among the many currently proposed energy storage solutions, electrolyzed water is considered the most potential energy storage means. The scheme generally refers to that hydrogen and oxygen are prepared by electrolyzing water by utilizing electric energy when the power generation wave crest is generated, and the electric energy is stored in chemical energy; and the electric energy is released by the reaction of hydrogen and oxygen in the trough period of power generation, so that the carbon emission problem is not involved in the circulation process, and the energy storage method is a real green energy storage mode. In addition, the generated hydrogen and oxygen can be used in other industrial production processes. At present, a great deal of research shows that catalysts containing noble metal elements, such as platinum, ruthenium and other noble metal catalysts, show very excellent performance in electrolyzed water, but the noble metals are expensive due to scarcity on the earth, and the cost of the process of storing energy in the electrolyzed water is seriously influenced. Therefore, a catalyst material with low cost, good catalytic effect and extremely high stability is sought, and the catalyst material plays a vital role in realizing industrial application of the electrolyzed water.
Current nickel-based catalysts are found in large laboratories by virtue of their non-noble metal properties and high performance catalytic effect. With continued research, researchers have found that the catalytic performance of nickel-based catalysts is greatly improved by incorporating iron into the catalysts. This may be due to the fact that the iron element is added to play a role in regulating the electronic structure of nickel, but the research on the mechanism of the regulation is still in debate. The electron transport and the proton transport in the electrolytic water catalysis process respectively represent the thermodynamic and kinetic characteristics of the reaction, and the two characteristics basically determine the rate problem of the electrolytic water. The thermodynamic property of the nickel-based catalyst is solved by doping iron element into the nickel-based catalyst, and the improvement of the kinetic property relates to the restructuring of a novel catalyst framework structure.

Test:
1. testing of LSV curves
LSV curve tests were conducted on the metal coordination polymer catalysts prepared in examples 1 to 5 and comparative examples 1 to 2 using a three-electrode system in which a platinum electrode was used as a counter electrode, the catalyst was used as a working electrode, and the reference electrode was a Hg/HgO electrode inserted in an electrolytic cell in such a manner as to be inserted transversely in the electrolytic cell and as close as possible to one end of the working electrode containing a NiFe-PMA catalyst. The test environment was an electrochemical test performed in 1M KOH electrolyte at room temperature using the electrochemical workstation Bio-Logic VMP3 FlexP 0160. The scan rates were all 5 mV/s. The voltage scanned ranged from 0V to 0.65V (V vs. Hg/HgO). The results are shown in FIG. 2. from FIG. 2, it can be seen that the catalyst Ni prepared in example 10.7Fe0.3PMA has a lower potential, so the optimal proportion of nickel and iron in the catalyst is Ni: fe-7: 3. Based on the conclusions drawn from this experiment, a catalyst with a NiFe ratio of 7:3 was therefore considered as the optimal catalyst, and subsequent testing and analysis were performed.
2. Infrared and Raman Spectroscopy testing
The infrared spectrum and raman spectrum of the catalyst sample prepared in example 1 and the sample after the electrochemical reaction were measured, and the results are shown in fig. 3. It can be observed from FIG. 3 that the prepared bimetallic complex polymer catalyst contains Carboxylate (COOH) and carboxylate ion (COO)-)。
3. Test for catalytic Performance
The catalytic performance and stability of the catalyst were tested in comparison with NiFe-LDH and Nickel foam (Nickel foam) prepared in comparative example, and the results are shown in FIG. 4. from FIG. 4a, it can be seen that NiFe-PMA has more excellent electrolytic water catalytic ability than conventional NiFe-LDH. The Tafel slope of FIG. 4b further illustrates the very outstanding performance of NiFe-PMA in electron transport rate. The stability tests of FIGS. 4c and 4d confirm the stable performance of NiFe-PMA during electrocatalysis.
4. Transmission Electron Microscopy (TEM) testing
The transmission electron micrograph was taken with a JEOL JEM-2100Plus apparatus. As shown in FIG. 5, it can be seen from FIG. 5a that the NiFe-PMA microstructure contains a large number of particles and a large number of carbon structures around the particles, which proves that the PMA forms coordination polymer with the Ni-Fe element, and the interplanar spacing of 0.25nm can also be seen in FIG. 5 a; the EDS scans in FIGS. 5C-g show the distribution of Ni, Fe, C, and O elements.
While the invention has been described with respect to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
