Self‐Encapsulation of High‐Entropy Alloy Nanoparticles inside Carbonized Wood for Highly Durable Electrocatalysis

Advanced Materials, Год журнала: 2024, Номер 36(28)

Опубликована: Апрель 26, 2024

High-entropy alloy nanoparticles (HEAs) show great potential in emerging electrocatalysis due to their combination and optimization of multiple elements. However, synthesized HEAs often exhibit a weak interface with the conductive substrate, hindering applications long-term catalysis energy conversion. Herein, highly active durable electrocatalyst composed quinary (PtNiCoFeCu) encapsulated inside activated carbonized wood (ACW) is reported. The self-encapsulation achieved during Joule heating synthesis (2060 K, 2 s) where naturally nucleate at defect sites. In meantime, catalyze deposition mobile carbon atoms form protective few-layer shell rapid quenching process, thus remarkably strengthening stability between ACW. As result, HEAs@ACW shows not only favorable activity an overpotential 7 mV 10 mA cm

Research Progress and Perspectives on Anti‐Poisoning Hydrogen Oxidation Reaction Electrocatalysts for Hydrogen Fuel Cells

Small, Год журнала: 2025, Номер unknown

Опубликована: Янв. 5, 2025

Abstract As global demand for clean and sustainable energy continues to rise, fuel cell technology has seen rapid advancement. However, the presence of trace impurities like carbon monoxide (CO) hydrogen sulfide (H₂S) in can significantly deactivate anode by blocking its active sites, leading reduced performance. Developing electrocatalysts that are resistant CO H₂S poisoning therefore become a critical priority. This paper provides comprehensive analysis mechanisms reviews key strategies developed over past few decades enhance impurity tolerance electrocatalysts. It begins examining differences oxidation reaction (HOR) acidic alkaline environments, focusing on roles binding (HBE) hydroxide (OHBE). Next, it outlines three main approaches mitigate poisoning: (I) bifunctional mechanisms, (II) direct (III) constructing protective layers. The review then shifts countering poisoning, emphasizing both electrocatalyst design structural improvements cells. Finally, highlights recent advances anti‐poisoning electrocatalysts, discusses their applications limitations, identifies challenges future opportunities further research this field.
