Boosting CO2 Selective Electroreduction to CH4 With High Efficiency Over Oxygen‐Riched Cu‐CeO2 Catalyst by Constructing Heterointerface Built‐in Electric Field

open access: yesEcoEnergy, EarlyView.
Defect‐rich Cu‐CeO2 heterojunction generates a strong built‐in electric field, accelerates directional electron transfer from CeO2 to Cu, and enables highly selective and efficient CO2 electroreduction to CH4. ABSTRACT Electrochemical CO2 reduction reaction (CO2RR) to CH4 offers a sustainable route for carbon neutrality, but it is hindered by sluggish ...

Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

CO2 Conversion Into Energy Rich Fuels Over Nascent COF Decorated‐Lead Free Halide Perovskites Hybrid Nano Catalysts: Experimental and Computational Investigation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A panoramic scheme signifies the CO2 conversion into energy‐rich fuels over nascent COF‐decorated lead‐free halide perovskite hybrid nano‐catalysts. Even though lead‐containing halide perovskites have been deemed emerging materials. However, the presence of toxic and carcinogenic lead (Pb) metal, small surface area, low charge separation, and a high ...

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 ...

Enhancing g‐C3N4 Photocatalytic Activity: K‐Doping and CuO Heterojunction for Selective CO2 Conversion to CH4

open access: yesElectron, EarlyView.
The CuO/K‐g‐C3N4 heterostructure photocatalyst achieves selective CO2 reduction to CH4 (93.03% selectivity) under visible‐light irradiation. K‐doping enhances crystallinity, whereas CuO forms a p‐n heterojunction to promote charge separation and electron transfer.

On the Structural Evolution Mechanism of Lignin‐Derived Hard Carbon for Refining Sodium‐Ion Storage

open access: yesElectron, EarlyView.
The lignin‐derived hard carbons with different microstructures were prepared under different carbonization temperature (600°C–1600°C) and carbonization time (0–6 h). The correlation between the local structure of all hard carbons and sodium‐ion storage performance was statistically analyzed. The optimized hard carbon anode has high‐rate performance and
