Problems solved by technology

Electrochemical energy conversion devices such as fuel cells, electrolysers, solar hydrogen generators, and electrochemical sensors have been developed to the commercial stage in acidic environments, but due to The use of platinum catalysts that are expensive and have limited reserves on the earth has hindered their widespread application; in order to overcome this dilemma, electrochemical energy conversion devices using non-platinum catalysts are the best alternatives, but they are limited by non-platinum catalysts in alkaline The electrochemical reaction speed in the environment is too slow, resulting in too low energy conversion efficiency, resulting in a lag in development

experiment example 1

[0062] X m Y alloy>

[0063] Containing different proportions (X / Y) of Ru in the preparation examples 1~7 X m Y The catalyst composition of the alloy was subjected to the aforementioned HOR test, and the results are shown in Figure 5 .

experiment example 2

[0067]

[0068] For preparation examples 4 and 8-10 containing different Ru X m Y The catalyst composition of alloy weight percent carries out aforementioned HOR test, and the result is shown in Image 6 .

[0069] In addition, the results of Comparative Examples 1 and 2 are also shown in Image 6 in as a comparison.

[0070] from Image 6 It can be seen that the reactivity of Preparation Examples 4 and 8-10 is significantly higher than that of Comparative Examples 1-2.

experiment example 3

[0074] X m Y alloy>

[0075] Containing different proportions (X / Y) of Ru in the preparation examples 1~7 X m Y The catalyst composition of the alloy was subjected to the aforementioned HER test, and the results are shown in Figure 8 .

[0076]

[0077] The aforementioned HER tests were performed using pure Ru and pure Ni that accounted for 20w% of the total mass of the catalyst composition, and the results are shown in Figure 8 .

[0078] from Figure 8 It can be seen that the reactivity of Preparation Examples 1-7 is higher than that of Comparative Example 2; the reactivity of Preparation Examples 1-6 is higher than that of Comparative Example 1.

Abstract

A catalyst composition and a use thereof are provided. The catalyst composition includes a support and at least one RuXMY alloy attached to the surface of the support, wherein M is a transition metal and X>=Y. The catalyst composition is used in an alkaline electrochemical energy conversion reaction, and can improve the energy conversion efficiency for an electrochemical energy conversion device and significantly reduce material costs.

Description

technical field [0001] The present invention relates to a catalyst composition, and in particular to a catalyst composition for alkaline electrochemical energy conversion reaction and its use. Background technique [0002] The hydrogen economy (hydrogen economy) is an energy structure based on hydrogen. First, the electricity converted from renewable energy such as solar energy, wind power, tidal energy, and geothermal energy is used to electrolyze water to generate hydrogen. The hydrogen is stored and transported to fuel cells for power generation. Replace the current oil economic system. Electrochemical energy conversion devices such as fuel cells, electrolysers, solar hydrogen generators, and electrochemical sensors have been developed to the commercial stage in acidic environments, but due to The use of platinum catalysts that are expensive and have limited reserves on the earth has hindered their widespread application; in order to overcome this dilemma, electrochemica...
