Cobalt iron phosphide nanoparticles embedded within a carbon matrix as highly efficient electrocatalysts for the oxygen evolution reaction

Co 3 FeP x /C nanocomposites were derived from one-step phosphorization of anthraquinone-2-sulfonate (AQS2) intercalated Co 3 Fe layered double hydroxides (Co 3 Fe LDHs). The carbonized AQS2 confines Co 3 FeP x nanoparticles in the amorphous carbon matrix during thermal treatment. Ultra-small and un...

Zusammenfassung:Co 3 FeP x /C nanocomposites were derived from one-step phosphorization of anthraquinone-2-sulfonate (AQS2) intercalated Co 3 Fe layered double hydroxides (Co 3 Fe LDHs). The carbonized AQS2 confines Co 3 FeP x nanoparticles in the amorphous carbon matrix during thermal treatment. Ultra-small and uniformly distributed Co 3 FeP x /C nanoparticles in carbon exhibit excellent durability and outstanding OER catalytic activity. Co 3 FeP x /C nanocomposites were derived from one-step phosphorization of anthraquinone-2-sulfonate (AQS2) intercalated Co 3 Fe layered double hydroxides (Co 3 Fe LDHs).
