Abstract
This invention belongs to the field of electrocatalysis, specifically relating to a high-entropy alloy heterostructure electrocatalyst, its preparation method, and its application. This invention prepares a nanoscale high-entropy alloy heterostructure electrocatalyst via a simple two-step low-temperature oil-phase method. The high-entropy alloy is distributed on carbon nanotubes and forms a heterostructure with Ni, adjusting the electronic structure and optimizing the hydrogen adsorption energy of the catalyst, making it an excellent electrocatalytic hydrogen evolution catalyst.
