Summary: A sequential self-templating method was used to synthesize CoNiFe trimetallic carbonate hydroxide hierarchical hollow microflowers with oxygen vacancies. These hollow microflowers exhibited high active-site exposure density and increased electrical conductivity due to their hollow structure, Fe substitution, and V-O. The optimized trimetallic carbonate hydroxide microflowers showed excellent performance in the oxygen evolution reaction with low overpotential and Tafel slope. Theoretical calculations revealed that Fe substitution and V-O could regulate the electronic states and achieve near-ideal adsorption/desorption capacity for oxygenated intermediates. The successful synthesis of other substituted carbonate hydroxides provides a general protocol to construct transition multimetallic electrocatalysts with hollow structures for highly efficient energy conversion reactions.

Summary: The rational composition design of trimetallic phosphide catalysts is crucial for enhancing surface reactions and improving catalytic performance. In this study, hierarchical CoxNiyFezP catalysts with precise control of stoichiometric metallic elements were synthesized. Among them, Co1.3Ni0.5Fe0.2P showed the most optimal composition, exhibiting remarkable catalytic activity and long-term stability for the oxygen evolution reaction (OER). It was found that the surface phosphorus in Co1.3Ni0.5Fe0.2P was replaced by oxygen under the OER process. Density functional theory calculations before and after long-term stability tests revealed an increase in the density of states near the Fermi level of Co1.3Ni0.5Fe0.2P/Co1.3Ni0.5Fe0.2O, which could enhance the adsorption of OH- and improve the OER performance of the catalyst.
