Rare‐Earth Yttrium Doping Advances High‐Performance AgSbTe2 Thermoelectrics

open access: yesAdvanced Energy Materials, Volume 16, Issue 30, 12 August 2026.
Y‐doped AgSbTe2 achieves band and microstructure co‐optimization, with coherent Y‐Ag2Te interfaces enhancing phonon scattering and reducing lattice thermal conductivity to 0.26 W m−1 K−1. Combined with valence‐band broadening and increased carrier concentration, this yields ZT ≈ 2 at 623 K, average ZT = 1.5, and 7.3 % conversion efficiency of a single ...

CH4 Synthesis From CO2 and NH3 Over Oxide‐Supported Ru Catalysts

open access: yesChemCatChem, Volume 18, Issue 15, 14 August 2026.
CO2 + NH3 methanation is a promising route to carbon‐neutral fuel synthesis. For oxide‐supported Ru catalysts, the basic character of the support strongly governs catalytic activity. Oxide supports with moderate basic character, such as ZrO2, prove optimal for CH4 production by facilitating both the destabilization of surface isocyanate species (NCO*),

Just Transition Toward Clean Energy Access With Focus on Lead‐Based Perovskite Solar Cell Technology: Lessons, Experiences, and Future Perspectives

open access: yesGlobal Challenges, Volume 10, Issue 8, August 2026.
To intentionally mitigate energy poverty in underserved communities, advanced perovskite energy technologies such as lead‐based perovskite solar cells are necessary. However, in future deployment of these materials, energy justice, equity, inclusivity and environmental sustainability must be taken into account.

Regulating Ligand‐to‐Metal Charge Transfer in UiO‐66(Zr)‐NH2 With Site‐Isolated Cu+ Centers for Efficient Photocatalytic H2O2 Generation

open access: yesSmall Science, Volume 6, Issue 8, August 2026.
Incorporation of highly dispersed Cu species into UiO‐66(Zr)‐NH2 introduces a competing ligand‐to‐Cu charge–transfer pathway that suppresses charge recombination and enhances photocatalytic H2O2 production. Combined PL, TRPL, TRIR, and variable‐temperature FTIR analyses reveal Cu‐mediated modulation of excited‐state dynamics and oxygen reduction ...
