Constructing Cu/Cu2O Heterogeneous Interface for Efficient Urea Electrosynthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this study, a Cu/Cu2O heterogeneous interface with dual active sites is prepared for electrocatalytic CO2 and NO3−$$ {\mathrm{NO}}_3^{-} $$ coupling to urea. The catalyst shows high yield rates of 1156.63 mmol g−1 h−1 and FE of 29.67% at −1.0 V (vs RHE), which is significantly higher than Cu and Cu2O, highlighting the advantages of heterogeneous ...

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

ENERGY &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 ...

Enhanced intermolecular coulombic decay due to sulfur heteroatoms in thiophene dimer

Communications Chemistry
Intermolecular Coulombic decay (ICD) is an important relaxation process of excited atoms and molecules in an environment, producing low-energy electrons that may contribute to radiation damage.

Graphene oxide/exfoliated black phosphorus van der Waals heterojunctions for PEDOT:PSS‐free‐based organic light‐emitting diodes achieving excellent electroluminescence performance

FlexMat, EarlyView.
A novel two‐dimensional heterojunction assembled from graphene oxide and exfoliated black phosphorus via van der Waals interactions is proposed to replace widely used poly(3,4‐ethylenedioxythiophene)‐polystyrene sulfonate for efficient hole injection layer in organic light‐emitting diodes, achieving impressive electroluminescence performance.
