Electronic State and Microenvironment Modulation of Metal Nanoparticles Stabilized by MOFs for Boosting Electrocatalytic Nitrogen Reduction

Lulu Wen et al.

Summary: In this study, PdCu nanoparticles were encapsulated into a sulfonate functionalized metal-organic framework, UiO-66-SO3H, and their microenvironment was further modified by coating a hydrophobic polydimethylsiloxane (PDMS) layer. The resulting PdCu@UiO-S@PDMS catalyst exhibited high activity towards electrochemical nitrogen reduction reaction (NRR), surpassing other counterparts. Experimental and theoretical results revealed that the protonated and hydrophobic microenvironment provided protons for NRR and suppressed the competitive hydrogen evolution reaction, while the electron-rich PdCu sites favored the formation of the N2H* intermediate and reduced the energy barrier of NRR, contributing to its excellent performance.

Engineering electrocatalytic fiber architectures

Fangzhou Zhang et al.

Summary: Recently, there has been a significant increase in demand for high-efficiency electrocatalysts for advanced energy conversion systems. One-dimensional fiber materials are considered promising electrode materials due to their excellent mechanical strength, large surface area, high electrical conductivity, compositional/morphological tunability, and structural stability. This article provides a detailed description of the design and synthesis of fiber-based electrocatalysts, including supportive fibers for catalyst loading and electrocatalytic fibers containing intrinsic active sites. The precise control of these architectures for specific electrocatalytic reactions and the future challenges and research directions of fiber materials for real-world energy conversion applications are discussed.
