Description
Technical Field
The invention relates to the technical field of electrochemical catalysis, in particular to a noble metal monoatomic catalyst based on a high entropy effect and a preparation method thereof.
Background
The energy is a basic stone for existence and development of human society, is a basic constraint condition for economic development and civilization progress, and is an important foundation for national economy and national security and sustainable development. Under the guidance of 'carbon peak, carbon neutralization', following the rapid development of new energy sources such as solar energy, wind energy and the like, hydrogen energy is coming out as a recognized zero-carbon energy source. The preparation technology of hydrogen mainly comprises fossil fuel hydrogen production, electrolytic water hydrogen production, photolytic water hydrogen production and biological hydrogen production.
The hydrogen production process by water electrolysis is simple, the product purity is high, and the high-efficiency, clean and large-scale preparation of hydrogen can be realized by adopting renewable energy sources as energy sources. However, electrolyzed water is a complex redox reaction process involving multiple electron transfer from the anode to the cathode, and thus the electrolyzed water catalyst is one of the key factors determining the cost of hydrogen production by electrolysis of water.
The most widely used in industry is alkaline water electrolysis technology at present, and under the current technical conditions, noble metal platinum and yttrium oxide/ruthenium oxide are respectively cathode and anode catalysts with higher catalytic efficiency, but the industrial application of the noble metal platinum and the yttrium oxide/ruthenium oxide is severely limited by the expensive price and poor stability of the noble metal platinum and the yttrium oxide/ruthenium oxide. Therefore, the water electrolysis catalyst for improving the utilization rate and the catalytic stability of the noble metal catalyst is a key for large-scale popularization of the core competitiveness of the technology.
The high-entropy hydroxyl oxide is a novel functional material which is derived and developed on the basis of high-entropy alloy and consists of oxygen ions, hydroxyl ions and five or more metal elements and has unique structure and function adjustable characteristics. In highly disordered multicomponent systems, high entropy oxyhydroxide produces a unique set of properties such as lattice distortion effects, high entropy effects, delayed diffusion effects, and cocktail effects due to the large mixing entropy.
In recent years, a single-atom composite material is used as a novel catalyst, and the noble metal atoms are anchored on a substrate, so that the atom utilization rate and stability of the noble metal can be greatly improved, and the single-atom composite material has a unique electronic structure and excellent catalytic performance and is becoming a research hot spot in the catalytic field. However, noble metal monoatoms have very high surface free energy, making them susceptible to agglomeration to form clusters and nanoparticles, and therefore the preparation of monoatomic catalysts is a challenge; meanwhile, on the other hand, the larger doping amount is easy to agglomerate to form clusters, but too low doping amount cannot ensure the number of the catalytic active sites, so that the activity of the single-atom catalyst is influenced to a certain extent. Therefore, the preparation method of the noble metal monoatomic catalyst with uniform scale and rich catalytic active sites is still in a research and development stage.
