Al, P-co-doping and interface engineering synergistically boost the electrocatalytic performance of WS₂/Ni₃S₂/NiS nanosheet heterostructure for efficient hydrogen evolution reaction.

ABSTRACT: The fabrication of earth-abundant electrocatalysts capable of facilitating hydrogen evolution reactions (HER) is essential for creating sustainable hydrogen fuel by water splitting. Here, we present a one-pot hydrothermal approach for producing aluminum and phosphorus co-doped NiS/Ni₃S₂/WS₂ heterostructure hybrid frameworks on nickel foam. The optimal Al and Al, P/NiWS-b@NF catalyst exhibits high HER activity with overpotentials of 139 and 227 mV at current densities of 10 and 50 mA cm^-2, respectively, thanks to the synergistic effect of the various constituents of the catalyst. What is more, it also exhibits a promising Tafel slope of 124 mV dec^-1 and is electrocatalytically durable for 10 hours in 0.5 M H₂SO₄ so
