Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 19, 2024

Abstract High entropy materials (HEMs) compositing of at least five elements have gained widespread attention in the field electrocatalysis due to their tunable activities and high stability. These intrinsic properties can be further highlighted when size HEMs comes nanoscale. In nanostructured HEMs, fascinating including large composition space, multi‐element synergy, configuration are expected endow nano‐HEMs with excellent catalytic activity stability, thus providing greater potential for design advanced electrocatalysts. this review, differentiated detail dimensions common synthesis methods summarized. Additionally, from perspective complex nanostructure‐performance relationship, applications systems, water‐splitting (hydrogen evolution reaction (HER), oxygen (OER)), hydrogen oxidation (HOR), reduction (ORR), carbon dioxide (CO 2 RR), nitrogen (NRR) alcohol (AOR) discussed. Finally, main challenges faced by underscored. This review is provide more insights into understanding developing efficient electrocatalytic practical applications.

Spatially Immobilized PtPdFeCoNi as an Excellent Bifunctional Oxygen Electrocatalyst for Zinc–Air Battery

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 20, 2024

Abstract Developing efficient oxygen electrocatalysts with low cost, high catalytic activity, and robust stability remains a formidable challenge for rechargeable zinc–air batteries (ZABs). Herein, highly dispersed ultrasmall PtPdFeCoNi high‐entropy alloy nanoparticles size of ≈ 2 nm randomly distributed multimetallic single atoms spatially immobilized on the 3D hierarchically ordered porous nitrogen‐doped carbon skeleton (denoted as PtPdFeCoNi/HOPNC) are successfully synthesized via ultra‐rapid Joule heating process. The spatial immobilization HOPNC is key to dispersion multi‐active sites electrocatalysts, formed hierarchical pore structure conducive successful construction rapid mass transfer channel. As result, as‐prepared PtPdFeCoNi/HOPNC exhibits positive half‐wave potential 0.866 V versus RHE reduction reaction (ORR), overpotential 310 mV at 10 mA cm −2 evolution (OER), Tafel slopes both ORR OER. Furthermore, ZAB using bifunctional catalysts excellent rate performances superior cycling stability, surpassing that commercial Pt/C‐RuO mixture. strategy provides new idea design synthesis various applications.
