Role of Lewis centres on ethanol dehydrogenation over the Cu‐Cr/γ‐Al2O3 system

The Canadian Journal of Chemical Engineering, EarlyView.
Cu–Cr interactions on alumina enhance Lewis acid site density, boosting selectivity towards ethanol dehydrogenation products. Soft coke formation on copper and Cu–Cr sites drives deactivation, shifting the reaction towards unwanted dehydration products.

Gradient p‐p Orbital Hybridization in Bismuth‐Doped Crystalline Carbon Nitride for Dual‐Functional Carbon‐to‐Carbon Valorization

EcoEnergy, EarlyView.
Schematic illustration comparing the charge transfer dynamics and catalytic reaction over the (left) pristine carbon nitride and (right) Bi‐doped carbon nitride photocatalysts. In the pristine system, random charge diffusion and rapid recombination limit catalytic efficiency. In contrast, the Bi‐doped system establishes a robust internal electric field

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 ...
