Natural Sunlight IR‐Driven Highly Efficient Synthesis of Acetaldehyde From Bioethanol Over Cu/Fe2O3

open access: yesAngewandte Chemie, EarlyView.
This work reports a Cu/Fe2O3 catalyst for the conversion of bioethanol into valuable acetaldehyde and green hydrogen under both infrared (IR) light and natural sunlight. This IR‐driven system sets a new performance benchmark, with TON and initial TOF enhanced by at least one order of magnitude, enabled by a constructed IR photon‐to‐phonon channel and ...

Trajetórias Desacopladas: Intensidade de CO₂ Fóssil, Emissões de Uso da Terra e Dinâmica Florestal na América do Sul (2000–2020)

open access: yes
South America combines extensive tropical forests and large land‑use carbon stocks with an energy system that is relatively low in fossil CO₂ intensity, due in part to widespread use of hydropower.
