Transitioning of the Chemical Industry Toward a Net-Zero Carbon Dioxide Emission Path. [PDF]
Angew Chem Int Ed EnglOne way to reduce the greenhouse gas footprint of the chemical industry to almost zero would be the production of the platform molecules C1‐compounds, olefins, aromatics, and ammonia by non‐fossil pathways. The rest of the chemical production chains could be essentially left unchanged, provided the process energy input is renewable.

TiO<sub>2</sub>-Supported Ru-Fe Catalysts for the Hydrodeoxygenation of Bis(2-hydroxyethyl) Terephthalate (BHET) Prepared by the Glycolysis of Polyethylene Terephthalate (PET). [PDF]
ChemSusChemPlastic waste serves as a source of petrochemical feedstocks. Bis(2‐hydroxyethyl) terephthalate (BHET) obtained from polyethylene terephthalate (PET) underwent hydrodeoxygenation to saturated C6–C8 cycloalkanes over Ru/Fe/TiO2. Proximity between Ru and Fe oxide depleted the electron density of Ru, modulated its catalytic activity, and suppressed ...
