Nonmetallic High‐Entropy‐Engineered Nanocarbons for Advanced ORR Electrocatalysis

Angewandte Chemie, Journal Year: 2025, Volume and Issue: unknown

Published: March 10, 2025

Abstract High‐entropy materials are poised to revolutionize science and industrial applications due their design flexibility, peculiar performance, broad applicability. In this study, we present a proof‐of‐concept high‐entropy engineered nanocarbon (HENC) co‐doped with five nonmetal elements (B, F, P, S, N), synthesized via in situ polymerization modification of ZIF‐8 followed by pyrolysis. The HENC exhibits outstanding performance as electrocatalyst for the oxygen reduction reaction (ORR), activity on par benchmark Pt/C electrocatalysts superior cyclic stability. Simulations all‐site calculations reveal that synergistic effects abundant heteroatoms increased system entropy facilitate formation *O 2 species, N, S acting key active elements, while co‐doping B F further enhances Notably, HENCs have been validated cathode catalysts zinc–air batteries, achieving an impressive peak power density 604 mW cm −2 demonstrating long‐term stability over 16‐day period, outpacing commercial catalyst (542 ). This work not only enriches concept high advances understanding but also opens new avenue development high‐performance low‐cost catalysts.

Recent Progress in Halogen‐Doped Single‐Atom Catalysts for Electrochemical Reactions

Carbon Neutralization, Journal Year: 2025, Volume and Issue: 4(1)

Published: Jan. 1, 2025

ABSTRACT Since the concept of single‐atom catalysts (SACs) was first proposed in 2011, related research has grown exponentially, establishing SACs as a highly active field. Compared to conventional supported nanoparticle catalysts, have attracted significant attention due their theoretically highest atomic utilization efficiency and tunable sites. Halogen atoms, with high electronegativity, possess strong electron‐withdrawing ability, enabling them powerful regulatory effect on Although there are numerous comprehensive high‐quality reviews SACs, specialized halogen‐doped is relatively scarce. Therefore, this article reviewed recent progress categorizing by four halogen atoms: fluorine (F), chlorine (Cl), bromine (Br), iodine (I). We also discussed application several key electrochemical reactions commonly relevant clean energy storage conversion, including hydrogen evolution reaction (HER), oxygen (OER), reduction (ORR), CO 2 (CO RR), elaborated corresponding mechanisms. Finally, paper presented prospects promote development catalytic activity.
