From nine to five: A compositional subtraction strategy to identify Ti as the key dopant in FeCoNiAl-based high-entropy catalysts for enhanced OER activity and stability

Conventional trial-and-error optimization of high-entropy compounds (HECs) for the oxygen evolution reaction (OER) is inefficient. Herein, we propose a “compositional subtraction” strategy to screen active components in a nine-metal HEC system (Fe, Co, Ni, Al, Ti, Cr, Mn, Cu, and...
