3‐Reactor Chemical Looping System for Point Source CO2 Capture and Subsequent Conversion for Liquid Fuel Production

EcoEnergy, EarlyView.
This study presents a novel 3‐reactor chemical looping system for CO2 capture and subsequent utilization with biomass and natural gas for producing liquid fuels. Using Ca2Fe2O5\Fe2O3 oxygen carriers, it achieves 60% CO2 capture efficiency, ∼80% syngas purity, and autothermal operation, offering a scalable, carbon‐negative route to sustainable fuels ...

A Mixed‐Ligand Metal–Organic Framework Strategy to Construct High‐Density O/S‐Shelled Ag Nanoparticle Electrocatalysts for Syngas Modulation

EcoEnergy, EarlyView.
Mixed‐ligand Ag–triazole MOF precursors reconstruct into ligand‐shelled Ag nanoparticle electrocatalysts that retain detectable O/S‐derived interfacial species. By combining ligand‐ratio and potential control, the CO2‐to‐syngas output can be tuned across H2‐rich, near‐equimolar, and CO‐rich regimes.

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

ENERGY &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 ...
