Description
Technical Field
The invention relates to the technical field of marine antifouling, in particular to a cobalt-based catalyst electrode and a preparation method thereof.
Background
With the observation of people on marine ecology and the development of marine resources, the development and utilization of various marine instruments and equipment are greatly promoted, so that the change of relevant characteristic parameters in the marine environment can be continuously monitored. However, when these equipments are exposed to seawater, biofouling inevitably occurs, which not only requires frequent cleaning and maintenance of the equipments, but also affects the collection of the relevant data. Therefore, finding an efficient, simple and controllable technique to solve the problem of biofouling of marine instruments is crucial to marine observation and utilization.
At present, the protection methods for marine instruments mainly comprise mechanical wiping, release of copper or tributyltin biocides, ultraviolet irradiation, chlorine preparation from seawater electrolysis, antifouling and the like. Among them, the technology of electrolyzing seawater to produce chlorine is concerned by people because of its advantages of simple operation, stability and high efficiency. On one hand, the method can control the generation amount of the effective chlorine, so that the method can prevent the biofouling of marine instruments and cannot cause damage to marine environment. On the other hand, seawater is rich in chloride ions, and the effective substances participating in the reaction are inexhaustible, so that the method also has excellent sustainability.
The most important technology for preparing chlorine and preventing pollution by electrolyzing seawater is the preparation and selection of electrodes. The chlorine industry commonly uses a Dimension Stability Anode (DSA) composed of Ru and Ir-based Mixed Metal Oxide (MMO) as a high-efficiency catalyst, and although the electrode has excellent catalytic chlorine evolution effect in the chlor-alkali industry, the marine antifouling property and the electrolysis condition of a chlorine production system are greatly different. The seawater electrolytic chlorine production antifouling is carried out under the conditions of typical neutral pH value and relatively low chloride ion concentration, and under the conditions, the DSA not only carries out chlorine evolution reaction, but also accompanies a large amount of oxygen evolution reaction. In addition, the electrode is made of precious metal materials and is expensive, which further limits the wide application of the electrode to seawater electrolysis. Therefore, the electrolytic seawater anti-fouling technology still needs to develop a chlorine evolution electrode with high activity, high selectivity and low cost.

Detailed Description
In order to facilitate an understanding of the invention, the invention is described in more detail below with reference to the accompanying drawings and specific examples. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Example 1: a cobalt-base catalyst electrode for preparing chlorine by electrolyzing seawater features that a Ti net is used as substrate on which the composite catalyst Co and Co (OH) is deposited2。
The cobalt-based catalyst electrode of this example was prepared by the following method:
(1) pretreatment of a titanium mesh: selecting titanium mesh as matrix, cutting into sample (1 cm × 3 cm) with fixed size, sequentially ultrasonic cleaning with acetone, ethanol and distilled water for 20min, drying at room temperature, packaging with Teflon adhesive tape to fix working area of 1cm2；
(2) Preparing a cobalt-based catalyst electrode: the preparation of the cobalt-based catalyst electrode is carried out at room temperature by adopting a constant voltage electrodeposition technology, a three-electrode system is used in an electrodeposition experiment, the treated titanium mesh is taken as a working electrode, a Saturated Calomel Electrode (SCE) and a platinum (Pt) mesh are respectively taken as a reference electrode and a counter electrode, and then the electrode is placed in 0.01M CoSO4Solutions ofAnd applying a voltage of-1.5V vs. SCE between the electrodes for 1200s, taking out the electrode after the voltage is finished, washing the electrode by using distilled water, and drying the electrode at room temperature to obtain the cobalt-based catalyst electrode.
The cobalt-based catalyst electrode for preparing chlorine by electrolyzing seawater, prepared in the above example 1, was subjected to morphology and composition characterization by SEM and XRD. From the SEM image of a cobalt-based catalyst electrode in FIG. 1, it can be seen that the cobalt-based catalyst electrode prepared in example 1 has a flower-like nanosheet structure, and the flaky structures are connected with each other, so that the structure has a larger specific surface area, can provide more reactive active sites, and is more beneficial to the electrocatalytic chlorine evolution reaction.
FIG. 2 is an XRD pattern of a cobalt-based catalyst electrode, which, by comparison with a standard XRD card, demonstrates Co-Co (OH)2Successful preparation of the catalyst.
FIG. 3 shows the results of chlorine evolution activity test of a cobalt-based catalyst electrode, and it can be seen from FIG. 3 that the electrode is compatible with Co of comparative example3O4The electrode (prepared by the method of the patent publication reference referred to 202110050042.6) exhibited more excellent electrocatalytic chlorine evolution activity in both 0.6M NaCl solution and saturated NaCl solution.
FIG. 4 is a graph showing the results of chlorine evolution performance tests of a cobalt-based catalyst electrode with DSA, showing that the current increase of the cobalt-based catalyst electrode in NaCl solution starts at 1.05V vs. SCE, but in Na containing no chloride2SO4The potential required for the oxidation current to occur in the solution was 1.23V vs. SCE. Meanwhile, for DSA, the current change trends in the two solutions are almost the same, which indicates that DSA has poor chlorine evolution selectivity in 0.6M NaCl solution. It can be seen that for marine environments (Cl)-The concentration is 0.6M), the cobalt-based catalyst electrode prepared by the method has high chlorine evolution selectivity.
