Defect‐Engineered Nested Metallic Cu Clusters Enhance CO2 Photoreduction in Photothermal 2D Plasmonic CuSe

EcoEnergy, EarlyView.
Solar‐driven photocatalytic CO2 conversion faces charge dynamics and spectral utilization limits. In this study, the nested Cu/CuSe heterostructure effectively enhances near‐infrared absorption, suppress charge carrier recombination, and improve CO production yield and selectivity through the photothermal–photocatalytic synergy. ABSTRACT Photocatalytic

Enhanced Hydrogen Evolution Reaction Performance of Ni‐Doped MoS2 with 1T Structure for Alkaline Water Electrolyzer: Introduction of 1T Phase and Morphological Optimization Through Co‐Sputtering Technique

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrogen evolution reaction activity of Ni‐doped MoS2 is enhanced by optimizing sputtering parameters in co‐sputtering. Sputtering power controls morphology and Ni doping which promotes 1T yield and activates basal planes. Sputtering time changes 1T yield regardless of Ni ratio.

Stepwise Optimization of Thermoelectric Performance in Cu3SbSe4‐Based Compounds via Alloying and Hierarchical Structuring

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Under the stepwise optimization strategy, (Sn, Te) co‐alloying functions as the primary initiative to enhance the power factor (PF), while the subsequent incorporation of AgCuTe operates as a synergistic maneuver to suppress lattice thermal conductivity (κlat), thereby concomitantly boosting the dimensionless figure of merit (ZT).
