Catalytic Hydrothermal Liquefaction of Polyethylene With Pt/C to Tune Product Selectivity

open access: yesCleanMat, EarlyView.
Pt/C‐catalyzed hydrothermal liquefaction of polyethylene in supercritical water enables time‐dependent control of product selectivity, producing paraffin‐rich oils at shorter reaction times and aromatic‐enriched products at longer times without external hydrogen. ABSTRACT Hydrothermal liquefaction (HTL) represents a promising thermochemical pathway for

Purification of Li2CO3 Obtained through Pyrometallurgical Treatment of NMC Black Mass from Electric Vehicle Batteries

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Lithium carbonate (Li2CO3) obtained from the black mass of recycled lithium batteries is dissolved in water under controlled conditions to remove lithium fluoride (LiF), which is present at a concentration of 3.08 % by weight. The dissolution is carried out at temperatures below 10 °C, and it has been demonstrated that lower temperatures result in ...

Toward a Paradigm Shift in Low‐Temperature SCR Catalyst Design: Defect Engineering and Data‐Driven Integration

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.
