High-entropy alloys (HEAs), with multi-principal-element composition, are gaining attention for their structural stability and mechanical properties. Extensive research has focused on using HEAs as electrocatalysts in the conversion of single-component reactions, such as hydrogen evolution reaction (HER), oxygen evolution reaction (OER), carbon dioxide reduction reaction (CO$_2$RR), etc. However, their potential in the application of synergistic conversion of pollutants (e.g., carbon dioxide (CO$_2$) and nitrogen oxides (NO$_x$)) has been largely overlooked. This review overviews HEAs' fundamental concepts and characteristics, and delves into their advantages in transition metals and optimization strategies for the synergistic conversion process. It offers a novel approach for sustainable environmental remediation and resource utilization.
