Abstract An ingenious and convenient rapid thermal annealing (RTA) strategy is proposed for large-scale synthesis of two-demensional (2D) oxide-fluoride nanoplates from different precursors. Taking the compatibility advantage of solution process, diverse metal cations can be further incorporated to stimulate multiple ion-modification and thus form polymetallic mixed-phase 2D nanomaterials. Due to the cation–anion regulation synergistic effect, ternary iron cobalt nickel oxide-fluoride (RH400-FeCoNi) exhibit excellent oxygen evolution reaction (OER) performance, superior to commercial IrO2 and other reported catalysts.
