V2CTx MXene as a Sacrificial Promoter for NiFe Catalyst for Anion Exchange Membrane Electrolyzers

open access: yesAdvanced Science, Volume 13, Issue 44, 7 August 2026.
These findings demonstrate that V2CTx functions beyond passive conductive support as an active electronic participant whose structural legacy sustains durable performance even after vanadium leaching in Anion Exchange Membrane (AEM) Electrolysers. ABSTRACT Nickel‐iron layered double hydroxides (NiFe‐LDH) show excellent activity, their poor conductivity

Boosting the Photocatalytic Performance of Layered Double Hydroxides by In Situ Reactions with Metal Nanoclusters

open access: yesAggregate, Volume 7, Issue 8, August 2026.
An interfacial engineering strategy based on in situ reactions between metal nanoclusters and layered double hydroxides enables simultaneous nanocluster size regulation, heterojunction construction, and mesopore generation. The reconstructed interface enhances visible‐light harvesting, charge separation, and mass transport, providing a general strategy

Efficiency of Superplasticizers in Low‐carbon Alkali‐activated Slag–Silica Fume Binders Governed by Polymer Solubility

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Workability control of alkali‐activated binders (AABs) remains an obstacle to producing low‐carbon clinkerless ultra‐high‐performance concrete, as their formulation usually necessitates low water‐to‐binder (W/B) ratios, high binder content, and concentrated activator solutions. To address this challenge, a greener and more manageable composite

Toward a Greener Production of Materials: Water‐Minimized Synthesis of NiAl‐, NiFe‐, and CoAl‐Layered Double Hydroxides for Photocatalytic CO2 Reduction

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.
This study provides a water‐minimized strategy to synthesize layered double hydroxides using resonant acoustic mixing. The catalysts’ CO2 reduction performance strongly depends on their physicochemical properties, which can be controlled during the synthesis.

Structure‐Sensitive Steam Reforming of Methane Over Exsolved NiAl‐Layered Double Hydroxides

open access: yesChemCatChem, Volume 18, Issue 13, 14 July 2026.
Exsolution of Ni nanoparticles from NiAl‐layered double hydroxides (LDH) provides a route to systematically control nanoparticle size in Ni/Al2O3 catalysts over the range of 4–18 nm. Methane steam reforming shows strong structure sensitivity, being favored over smaller (<10 nm) particles with 80 % methane conversion and a high specific hydrogen ...

Investigation of the Nickel‐Ceria Synergy for Efficient CO2 Methanation Under Nonthermal Plasma Activation

open access: yesChemCatChem, Volume 18, Issue 14, 29 July 2026.
Nickel‐ceria based catalysts displayed high performances for the methanation reaction achieving both high selectivity and conversion under non‐thermal plasma. These performances arose from the formation of the Ce1‐xNixO2‐γ solid solution promoted by the use of sol‐gel based synthesis and was investigated by XPS, TEM, TPR and raman.
