Description
Technical Field
The invention belongs to the technical field of electrocatalytic hydrogen evolution, and relates to a carbon-supported RhNi-Ni (OH)2A preparation method of (rhodium nickel-nickel hydroxide) composite hydrogen evolution electrocatalyst.
Background
Hydrogen is considered to be one of the ideal alternatives to fossil fuels as a clean, efficient renewable energy source. The hydrogen evolution reaction is a half-reaction of electrolysis of waterIs one of the important ways to prepare hydrogen. However, since the overvoltage of the hydrogen evolution reaction is high and a large amount of electric energy is consumed, it is necessary to develop an electrocatalyst having excellent catalytic performance to lower the energy barrier of the hydrogen evolution reaction. The hydrogen evolution catalyst with outstanding catalytic performance is mainly a noble metal catalyst, and the performance of the platinum-based catalyst is the most excellent at present. The hydrogen production reaction by water electrolysis is mostly carried out in alkaline solution, and for bulk phase catalyst, the catalytic activity of platinum in alkaline environment is nearly two orders of magnitude lower than that in acidic condition, while the catalytic activity of rhodium in alkaline and acidic solution is only about one order of magnitude different (see Jie Zheng, et al, Universal dependence of hydrogen oxidation and hydrolysis activity of platinum-group metals on pH and hydrogen generation, Sci.adv.,2016,2: e 1501602). Therefore, by regulating and controlling the components, the morphology and the structure of the rhodium-based catalyst, the hydrogen evolution catalytic performance more outstanding than that of a platinum catalyst in an alkaline solution is expected to be obtained. Currently, researchers have prepared Rh-based hydrogen evolution catalysts with excellent performance in alkaline environment, such as RhNi nano-sponge, Rh nanosheet, Rh nanoflower and the like, by regulating and controlling the morphology and components of the catalysts. However, the proportion of the noble metal element Rh in the Rh-based hydrogen evolution catalyst is still high, which is not favorable for reducing the production cost. Therefore, the development of a method for preparing the Rh-based hydrogen evolution catalyst with lower price has very important practical significance. Studies have found that the hydrogen evolution catalytic performance of noble metals in alkaline solutions can be greatly improved when transition metal hydroxides interact with noble metals (see the document Huajie Yin, et al, Ultrathinpnpinum nanowaus growth on single-layered aqueous reaction activity, Nature Communications,2015,6: 6430). In addition, the cost can be reduced by adding non-noble transition metal alloy elements into the noble metal catalyst, and the catalytic activity can be improved by the synergistic action of different elements. Based on The above theory and research foundation, The present invention provides a new idea of bright (Yu Chen, et al, The electrochemical performance of carbon ball supported RhCo allophanatities for The methanol oxidation reaction in alkalene media, Journal of Power Source, 2017,371)129-135) preparation of RhCo/C methanol oxidation electrocatalyst, research and development of RhNi-Ni (OH)2a/C hydrogen evolution electrocatalyst.

RhNi-Ni (OH) prepared by the method2The composite catalyst shows good hydrogen evolution catalytic activity in alkaline solution. When the current density is 10mA cm-2When the catalyst is used, the hydrogen evolution overpotential is even higher than that of a Pt/C catalyst, so that the catalyst has good industrial application prospect.
The invention has the following beneficial effects:
(1) the carbon carrier is subjected to heat treatment in an inert gas environment, so that pollutants on the surface of the carbon black can be decomposed, and the content of oxygen-containing functional groups on the surface is increased, so that the dispersity of the catalyst particles on the surface is effectively improved. Compared with other preparation methods, the method does not need high-temperature acid washing on the carbon carrier, thereby avoiding the volatilization of corrosive gas and the generation of toxic gas, and shortening the preparation time and difficulty.
(2) The invention mixes transition metal hydroxide Ni (OH)2The catalyst is combined with metal alloy RhNi to form a composite catalyst, so that compared with a commercial Rh/C, Pt/C catalyst, the use amount of noble metals in the preparation process is greatly reduced, and the production cost is obviously reduced.
(3) The carbon ball prepared by the invention loads RhNi-Ni (OH)2The composite catalyst exhibits better hydrogen evolution activity in alkaline solution than commercial Pt/C catalysts, e.g., when the current density is 10mA cm-2When the catalyst is used, the hydrogen evolution overpotential is higher than that of a Pt/C catalyst, so that the catalytic efficiency of the catalyst is higher than that of the Pt/C catalyst.
