Circular Economy durch moderne Chemie – aktuelle Forschung zu Nachhaltigkeit experimentell im Schülerlabor erfahren

open access: yesCHEMKON, EarlyView.
Die Circular Economy gilt als zentrales Leitbild für eine nachhaltige Ressourcennutzung und sollte daher stärker in der naturwissenschaftlichen Bildung verankert werden. Der Artikel stellt ein Schülerlaborprogramm im TüChemLab vor, das Schülerinnen und Schülern den Beitrag moderner Chemie zu einer Circular Economy anhand aktueller Forschung vermittelt.

Fluorescent Colored Passive Radiative Cooling Based on Carbon Dots for Cooling Power Recovery

open access: yesEcoEnergy, EarlyView.
We demonstrate colored passive radiative coolers consisting of a highly reflective porous ceramic base covered by an eco‐friendly luminescent carbon dot‐polymer composite, with two types of carbon dots enabling conversion of either ultraviolet or visible light, respectively.

Enhancing the Ferroelectricity of MAPbI3 via Hydroxyl Groups to Boost Photocatalytic Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydroxyl groups in (EOA)2PbBr4 enable a rearrangement of the polar MA+ ions in MAPbI3, which enhances the Ps‐electric field and promotes the separation of photogenerated carriers. Consequently, the (EOA)2PbBr4/MAPbI3 composite exhibits the enhanced CO production yield in photocatalytic CO2 reduction reactions.

Synergistic CNT‐Integrated Ni‐Phthalocyanine/g‐C3N4 Heterojunctional Photocatalysts With Single Ni–N4 (II) Sites for Efficient Ammonia Synthesis

open access: yesElectron, EarlyView.
We present a tandem nickel phthalocyanine (NiPc)/CNT‐P&Cu‐BCN photocatalyst, engineered with an organic–organic heterojunction for enhanced nitrogen conversion. This system integrates boron‐doped (B) nitrogen‐deficient (N) carbon nitride (CN), modified via Cu–Cu coordination and phosphorus doping through sodium borohydride‐assisted thermal treatment ...

Spirobifluorene fusion in multiple resonance frameworks enables efficient pure‐red OLEDs with narrowband emission and suppressed efficiency roll‐off

open access: yesFlexMat, EarlyView.
An orthogonal spirobifluorene‐fusion strategy is introduced for B/N/O‐alternated MR frameworks, enabling improved kRISC (5.46 × 103 s−1), high ΦPL (97%), and narrow‐band pure‐red emission. Vacuum‐evaporated OLEDs incorporating this emitter achieve an EQEmax >40% (FWHM = 36 nm) and exhibit exceptionally low efficiency roll‐off at high luminance ...
