CO2‐Driven Synthesis of Holey Edge‐Carboxylated Graphene for Tunable Electronic Interactions in Cu–CeO2‐Catalyzed Water‐Gas Shift Reaction

open access: yesCarbon Energy, EarlyView.
Holey‐structured, edge‐carboxylated graphene with a controlled specific surface area was synthesized using an environmentally friendly, CO2‐activated, KOH‐free ball‐milling process. ABSTRACT Graphene, notable for its high specific surface area, is ideal for catalyst support but faces challenges under harsh thermal catalytic conditions.

Ultrafast Transitions in X‐Ray Irradiated Solids

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Ag‐Regulated Cu‐Sites on a Conductive Cu‐Metal‐Organic Framework for Enhanced CO2 Electroreduction to CH4

open access: yesEcoEnergy, EarlyView.
We present a strategy of integrating Ag NPs with a 2D Cu3(HHTP)2 framework to boost selective CO2 electroreduction. The optimal composite achieves 65.1% FECH4 ${\text{FE}}_{{\text{CH}}_{4}}$ at 240 mA cm−2. Synergistic effects enhance CO2 adsorption, facilitate electron transfer, and selectively stabilize key reaction intermediates, steering the ...

Ullmann‐Type N‐Heteroarylation of Nitrogen Heterocycles Catalyzed by Heterogeneous CuNPs/HKUST‐1

open access: yesEcoEnergy, EarlyView.
A practical strategy for the direct synthesis of CuNPs/HKUST‐1 heterogeneous catalyst was developed and used for the catalyzing Ullmann‐type N‐arylation of N‐heterocycles with high yields, excellent recyclability, and low copper leaching. ABSTRACT Ullmann‐type C–N coupling is an essential reaction to construct functional nitrogen heterocycles, whereas ...

Synergistic‐Induced Perovskite Phase Distribution and Lattice Stabilization for Efficient and Stable Sky‐Blue PeLEDs

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We have developed a multifunctional buried‐interface engineering strategy using phenethylammonium thiocyanate to regulate quasi‐2D perovskite crystallization and stabilize the lattice. The synergistic effects of SCN− and PEA+ steric confinement promote phase redistribution toward n = 2, suppressing interfacial defects and enabling the production of ...
