Covalently Bonded S‐Scheme Polymer Heterojunction for Highly Efficient Solar Hydrogen Evolution

EcoEnergy, EarlyView.
A covalently integrated all‐organic S‐scheme heterojunction (B‐CN2@Py‐CN) establishes atomic‐level charge transport channels and a strong built‐in electric field, enabling exceptional charge separation efficiency. This molecularly engineered photocatalyst achieves a cocatalyst‐free hydrogen evolution rate of 27.9 mmol g−1 h−1 under visible light ...

Selective Optical Properties of Cement for Enhanced Radiative Cooling and Energy‐Efficient Construction Materials

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cement phases are good materials for radiative cooling thanks to the selective emissivity in IR ATW. Cement powders have high reflectance of solar radiation which reduces the thermal losses. The onset of the absorption curves is defined by bound excitons. Sulfates have higher radiated powers and reflectance than calcium silicates.

Strong Nonradiative Recombination Induced by Pronounced Lone‐Pair Electron Expression Following Deprotonation in Aziridinium Lead Iodide Perovskites

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The transition from linear to cyclic organic cations promotes deprotonation and activates VH(N) defects with pronounced lone‐pair electron activity, thereby inducing severe local distortions and highly efficient nonradiative recombination centers. This work unveils a direct structure–defect–performance correlation and proposes design strategies for the

Rational Design of CdS QDs/CeO2 Nanocube S‐Scheme Heterojunctions for Highly Efficient C2H4 Scavenging in Fresh Produce Preservation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel S‐scheme heterojunction of CdS quantum dots on CeO2 nanocubes was designed to enhance charge separation and oxygen activation for efficient photocatalytic ethylene removal. The optimized composite achieved complete C2H4 degradation within 4 min under low‐intensity visible light, with a rate constant of 1.72 min−1. Mechanistic analysis confirmed
