Synergistic Catalysis for Closed‐Loop Alcohol Refining: Concurrent H2 Evolution and Selective Oxidation

open access: yesEcoEnergy, EarlyView.
Photocatalytic, electrocatalytic, and photoelectrocatalytic systems exhibit a clear synergistic integration logic in closed‐loop alcohol refining—concurrently driving hydrogen evolution and selective alcohol oxidation to enable the directed conversion of alcohols into high‐value chemicals.

A Slot‐Interlocking Modular Flexible Thermoelectric Device Based on High‐Performance Bi2Te3 Thin Films for Wearable Energy Harvesting

open access: yesEcoEnergy, EarlyView.
We report a 30 × 38 mm2 flexible thermoelectric device based on vertically aligned p/n Bi2Te3 thin films with high power factors of 31.0 and 20.3 μW cm−1 K−2. An optimized device geometry achieves a high normalized power density of 3.5 μW cm−2 K−2 through efficient thermal management, while maintaining excellent stability and modular scalability ...

Transient Charging Dynamics in Stacked Ga2O3/ZnO Photovoltaic Units Governing Wavelength‐Selective Polarity Switching

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reveals a “Photovoltaic‐Capacitance” coupling mechanism in stacked Ga2O3/ZnO devices, defining the ZnO/graphene interface as a novel Photovoltaic Dynamic‐Capacitor (PDC). The wavelength‐selective bipolar response enables a physical layer secure communication protocol based on ternary optical logic (“1,” “0,” “−1”).

Rapid Joule‐Heating‐Induced Non‐Equilibrium Exsolution in Perovskite Oxides for Enhanced Photothermal CO2 Methanation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Rapid Joule heating induces Ni—Fe exsolution from perovskite oxides, forming Ni–Fe/oxide heterointerfaces that enhance photothermal CO2 methanation activity and selectivity. Achieving selective CO2 methanation under photothermal conditions requires catalysts capable of maintaining non‐equilibrium interfacial states that balance reduction and oxidation ...

MOF‐Derived Superaerophobic Ni‐CoOOH Nanosheet Anchored on Stretched Carbon via In Situ Morphology Reconstruction for Durable Oxygen Evolution

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study constructed an in situ superhydrophobic OER catalyst with excellent activity and durability. Ni‐Co expansion induced tensile strain, converting the polyhedral framework into vertical nanosheets that enhance intrinsic activity and bubble detachment.
