中国科研团队合成一种新型合金 助力电解水产氢

Core Insights - The research team at Anhui Normal University has successfully created sub-nanometer high-entropy alloys using laser irradiation, which allows for the mixing of up to ten different metal elements [1][2] - This innovative method overcomes traditional synthesis limitations by enabling uniform mixing of metals at mild conditions, resulting in smaller particle sizes [2] Group 1: Research Methodology - The team utilized nanosecond pulsed laser technology to rapidly heat particles to over 2000 degrees Celsius and then cool them at a rate exceeding one billion degrees per second, facilitating the creation of sub-nanometer high-entropy alloy particles [2] - This rapid heating and cooling process allows for the uniform dispersion and alloying of different metal elements, which was previously challenging due to the need for high temperatures and limited element combinations in traditional methods [2] Group 2: Applications and Implications - High-entropy alloys exhibit significant potential in various fields, particularly in renewable energy, serving as promising catalyst materials [2] - The newly developed laser synthesis method broadens the range of materials available for high-entropy alloys, potentially enhancing their application in critical areas [2] - The sub-nanometer high-entropy alloy composed of gold, platinum, ruthenium, rhodium, and iridium has demonstrated excellent hydrogen and oxygen production activity and stability as an electrolytic water catalyst [2]
