Description
Technical Field
The invention belongs to the technical field of synthesis and application of catalysts, and particularly relates to a preparation method of a metal organic gel with electrocatalytic performance and application of the metal organic gel in electrocatalytic methanol oxidation.
Background
The direct methanol fuel cell is a proton exchange membrane fuel cell taking methanol as liquid fuel, and has the advantages of rich fuel source, low price, convenient and safe storage and transportation and the like, and the methanol has high energy density and is widely concerned. However, the development of methanol fuel cells is limited by the slow reaction kinetics of the anode methanol reaction and the susceptibility of the platinum metal catalysts to poisoning, which requires increased platinum loading. Therefore, the number of exposed active sites of the catalyst, the surface structure, the composition and the atomic arrangement are very important for improving the utilization rate and the catalytic performance of the platinum. At present, a great deal of research is focused on exploring the formation of alloy or heterostructure catalysts of different transition metals and platinum so as to modify a platinum electronic structure and achieve the purposes of reducing the platinum loading capacity and improving the platinum utilization rate. The open-pore structured nanomaterial such as nanocages, nano frames, hollow spheres and the like also maximizes the utilization of the active metal to reduce costs by imparting a high specific surface area, porosity to the catalyst and an active surface with which the reactants can come into contact in three-dimensional directions. The Metal Organic Gels (MOGs) are expanded on the basis of the structure of metal organic framework Materials (MOFs), and the metal organic framework material particles can form a three-dimensional network structure in a self-assembly mode. Therefore, MOGs become a porous metal organic material with a hierarchical structure, and the porous metal organic material has the characteristics of high specific surface area, size-adjustable pore channels, low density, inherent metal sites and the like, so that the porous metal organic material has potential application values in the aspects of mass transfer, adsorption, catalyst carrier and the like. As one of the porous materials, it has a characteristic that the pore diameter is adjustable as compared with an inorganic porous material (e.g., molecular sieve), which is generally fixed in pore size. Compared with the hotter MOFs (also belongs to a porous material) researched in recent years, the metal organogel has the characteristics of large pore diameter and stability, and for the MOFs, in order to obtain larger pore diameter, the length of a ligand is the most commonly used method, but the synthesized MOFs are unstable when the ligand is increased, so that the application of the MOFs is greatly limited. Therefore, the synthesis and performance research of the metal organogel have good application prospects. In general, a noble metal material is often used as an electrode material of a methanol fuel cell, but the noble metals Pt and Pb are expensive, have a small storage amount, and are easily poisoned by being combined with a CO intermediate. The alkaline direct methanol fuel cell can utilize non-noble metals Ni and Cu as electrode materials, but Ni and Cu react with ligands to generate MOF, so that gel cannot be formed generally, the yield of the electrode materials is too low, the use cost is increased, and the synthesis process of the MOF is complex and long in time consumption. Therefore, in the invention, the methanol oxidation performance of the MIL-53(Al) metal organic gel is improved by utilizing the multi-metal synergistic effect through synthesizing the MIL-53(Al) metal organic gel and introducing nickel/copper into the MIL-53(Al) metal organic gel.
Disclosure of Invention
The invention provides a method for preparing single metal, double metal and tri-metal organogel materials, and the composite material is applied to electrocatalytic methanol oxidation, and the preparation method is simple and convenient and has high yield. The invention aims at the application of polymetallic organogel in the field of methanol oxidation, and provides a preparation method and application of an electrocatalytic material, namely an aluminum-monometallic organogel material 1, an aluminum/nickel-bimetallic organogel material 2 and an aluminum/nickel/copper-trimetallic organogel material 3, which are obtained by assembling terephthalic acid and aluminum, nickel and copper metal ions.
The purpose of the invention is realized by the following technical scheme, the three materials are an aluminum-single metal organogel material 1, an aluminum/nickel-double metal organogel material 2 and an aluminum/nickel/copper-triple metal organogel material 3 which have stability in a 0.1M KOH solution, and the three materials are prepared by a hydrothermal method and comprise the following steps:
(1) dissolving metal salt in N, N-dimethylacetamide solvent, and performing ultrasonic treatment to obtain a mixed solution.
(2) Dissolving terephthalic acid in N, N-dimethylacetamide solvent, and performing ultrasonic treatment to prepare a ligand solution containing terephthalic acid.
(3) And (3) pouring the solution obtained in the step (1) into the solution obtained in the step (2), performing ultrasonic treatment at room temperature for a period of time to fully mix the solution, transferring the mixture into a reaction kettle, and reacting at the temperature of 120-.
(4) And (4) washing the wet gel obtained in the step (3) with ethanol for three times to obtain an MIL-53-based aluminum-single metal organic gel material 1, an aluminum/nickel-double metal organic gel material 2 and an aluminum/nickel/copper-triple metal organic gel material 3.
The metal salt is aluminum nitrate or nickel nitrate or copper nitrate.
The amount of the N, N-dimethylacetamide is only needed to be immersed in the metal salt and the terephthalic acid, and the molar ratio of the aluminum nitrate and/or the nickel nitrate and/or the copper nitrate to the ligand terephthalic acid is 1-2: 1.
3 kinds of metal organic gel materials prepared by the steps are used as electro-catalysts to carry out electro-catalytic methanol oxidation tests. The method comprises the following specific steps:
1) weighing 4mg of the obtained metal organogel material, adding 0.2ml of naphthol, 1.3ml of deionized water and 0.5ml of ethanol, and carrying out ultrasonic mixing for 30min to prepare an electrode solution for later use.
2) Coating 4 microliter of the electrode solution obtained in the step 1) on a glassy carbon electrode to form a working electrode, taking a platinum wire as a counter electrode and taking a Hg/HgO electrode as a reference electrode to form a three-electrode system, and inserting the three-electrode system into electrolyte to perform methanol oxidation reaction.
The invention has the following advantages:
(1) the gel synthesized by the method has simple reaction conditions, is easy to repeat mass synthesis, and has lower cost. The method synthesizes the aluminum-nickel-containing bimetallic gel and the aluminum-nickel-copper trimetal gel, provides reference for simplifying the preparation process and synthesizing other gels of different metal types, and has certain guiding significance.
(2) The metal in the multi-metal organogel has synergistic effect (geometric effect and electronic effect), and the introduction of nickel/copper can effectively enhance the methanol oxidation performance of the catalyst.

Wherein the scan and energy spectra further reflect the presence of MIL-53(Al), MIL-53(AlNi) and MIL-53 (AlNiCu).
Example 4
The samples collected in examples 1-3 were weighed to 4mg respectively in a 4ml sample tube, added with 0.2ml naphthol, 0.5ml absolute ethyl alcohol and 1.3ml deionized water, and applied on a glassy carbon electrode after 30min of ultrasonic treatment.

The cyclic voltammogram of the metal organogel material in 0.1M potassium hydroxide and 1M methanol solution was tested for material Methanol Oxidation (MOR) performance as shown in FIG. 8, MIL-53(Al) gel has no methanol oxidation peak, and MIL-53(AlNi) gel has a lower peak than MIL-53 (AlNiCu). Wherein the oxidation peak overpotentials of MIL-53(AlNi) and MIL-53(AlNiCu) are 0.831V and 1.008V respectively, and the mass activity is improved from 909mA/mg to 1014 mA/mg.
