Recent studies have demonstrated the potential of high-entropy and medium-entropy materials in enhancing the catalytic hydrogen evolution reaction (HER) performance. High-entropy carbide (HEC) nanoparticles, in particular, have exhibited remarkable catalytic activity and durability for HER. This phenomenon can be attributed to the unique microstructure of these nanoparticles, which is coupled with enhanced electronic effects resulting from high configurational entropy . The high-entropy strategy employed in 2D metal phosphorus trichalcogenide (MPCh3) nanosheets has been shown to enhance HER performance, with an overpotential of 65.9 mV at 10 mA cm-2 and a Tafel slope of 65.5 mV dec-1 . This enhancement can be attributed to the optimization of active sites and the promotion of water dissociation during the Volmer step.
