The catalytic performance of oxygen evolution reaction (OER) catalysts is influenced by their elemental composition. Aluminum (Al) offers abundant active sites due to its high oxidation affinity, which makes it unstable in both acidic and alkaline environments. We used the gas atomization method (GAM) prepare aluminum-containing single-phase high-entropy alloy AlxCoCrFeNi2.1 (x = 0, 0.1, 0.3, 0.5, 1). Besides, changing aluminum content HEAs can control particle size. GAM enable with different Al contents present body-centered cubic (BCC) structure, avoiding phase separation caused other component smelting method. As predicted theory, as increases, AlCoCrFeNi2.1 shows best OER (overpotential ≈313 mV for 1000 h at 100 mA·cm–2). Furthermore, through precise weight detection system, COMSOL simulations, Density Functional Theory (DFT) calculations, we have further demonstrated superiority catalysis. Overall, this work provides a streamlined way slow down dissolution water electrolysis contributes controllable choice more element-dependent scenarios.

Abstract Carbon‐free dual‐atom catalysts (CFDACs) are beginning to make their presence in the field of electrocatalysis due unique properties and structures that different from those carbon‐based DACs, which endowed with activity, selectivity, stability. Currently, some advances made study CFDACs, including structure‐performance relationships metal‐support interaction, theoretical combined experiments, electrocatalytic applications potential catalytic mechanisms, design strategies achieve highly active performance. Herein, perception CFDACs is first elaborated terms carbon‐free substrates sites, then briefly summarizes advanced characterization techniques, study, energy storage conversion applications, highlights realize high‐performance vacancy anchoring, strain regulation, alloying, finally put forward personal viewpoints on current challenges future development CFDACs.
