Producing green hydrogen in a cost-competitive manner via water electrolysis will make the long-held dream of economy reality. Although platinum (Pt)-based catalysts show good performance toward evolution reaction (HER), high cost and scarce abundance challenge their economic viability sustainability. Here, non-Pt, high-performance electrocatalyst for HER achieved by engineering fractions stacking fault (SF) defects MoNi

Developing non-platinum group metal catalysts for the sluggish hydrogen oxidation reaction (HOR) is critical alkaline fuel cells. To date, Ni-based materials are most promising candidates but still suffer from insufficient performance. Herein, we report an unconventional hcp/fcc Ni (u-hcp/fcc Ni) heteronanocrystal with multiple epitaxial heterointerfaces and coherent twin boundaries, generating rugged surfaces plenty of asymmetric convex sites. Systematic analyses discover that such sites enable adsorption *H in unusual bridge positions weakened binding energy, circumventing over-strong on traditional hollow positions, simultaneously stabilizing interfacial

Abstract Membrane‐based gas separation offers notable energy efficiency benefits for hydrogen purification, yet it is often hindered by the inherent trade‐off between permeability and selectivity. To address this challenge, a novel mixed matrix membrane (MMM) design presented to boost H 2 performance via continuous spillover mechanisms first time. The MMM incorporates palladium‐functionalized ZIF‐67 gel (Pd@ZIF‐67 gel) network into polymer of intrinsic microporosity (PIM‐1) matrix. serves as uniform dispersion medium palladium nanoparticles (Pd NPs), thereby generating multitude active sites. These exposed sites, in conjunction with microporous structure ZIF‐67, facilitate dissociation establish pathway throughout membrane. This synergistic leads substantial improvements both transport At an optimal loading 28 wt% Pd@ZIF‐67 gel, MMMs exhibit 3620 Barrer remarkable 417% enhancement /CH 4 selectivity (24.9), surpassing 2008 upper bound. approach paves way development advanced materials tailored applications.

ABSTRACT Ammonia has gained considerable attention as a promising energy carrier due to its high hydrogen content, carbon‐free emissions, and ease of storage transportation compared gas. The electrochemical ammonia oxidation reaction (AOR) is pivotal process for harnessing sustainable source, enabling production through decomposition or electricity generation via direct fuel cells. NiCu, transition metal alloy, shown great potential an efficient cost‐effective catalyst AOR. In this study, high‐valence Ni Cu hydroxyl hydroxides were synthesized on nickel foam form NiCuOOH in the structure folded nanosheets, serving anodic electrocatalyst Comprehensive characterization identified metals primary active components. By optimizing Ni/Cu ratio, achieved remarkable performance stability, reaching maximum current density 169 mA cm − 2 at 1.62 V versus RHE, with 0.16 at% delivering activity, being stable 48 h 100 −2 . Additionally, exhibited excellent catalytic activity oxygen evolution (OER), attaining 152 1.72 RHE. This study presents cost‐effective, high‐performance, easily bifunctional self‐supporting catalyst, offering significant both AOR OER applications.
