Abstract The energy industry has taken notice of aluminum ion batteries (AIB) for their low cost, high safety, and capacity. However, using the ionic liquid electrolyte results in uneven Al electrodeposition reliance on expensive glass fiber separators, due to sluggish mass transport wettability polypropylene separator. Herein, a mixed is introduced by incorporating co‐solvent fluorobenzene into traditional AlCl 3 /1‐ethyl‐3‐methylimidazolium chloride liquid, which (FB) mitigates electrostatic interactions between ions facilitates diffusion. optimization principle proposed based maximizing transportation, as indicated limiting current density. optimized IL‐FB (1:5) offers highest density 12 mA cm −2 , highly reversible plate/stripe Al, thus stable cycling 7500 h with capacity (8 8 mAh ). Furthermore, also shows enhanced AIB separator, exhibiting 60% decrease achieved first time (1:5), presenting crucial step toward initial practical application.

Insights into Chemical Recycling and Upgrading Strategies for Polyolefin-Based Plastics

Industrial & Engineering Chemistry Research, Journal Year: 2025, Volume and Issue: 64(11), P. 5765 - 5781

Published: March 5, 2025

Plastic waste, particularly the dominant polyolefins, presents a growing environmental issue due to its chemical stability and low recycling rates. Although various methods are proposed address plastic strong carbon–carbon bonds within as well degradation of mechanical strength additional value by conventional methods, pose great challenges their downstream usage. With this regard, paper emphasizes polyolefins into renewable resources, including carbon materials, liquid fuels, hydrocarbon chemicals, thermal catalytic methods. An in-depth discussion on feasibility limitations promising techniques is provided, such association between reactor design, process optimization, catalyst preparation, product distribution. Specifically, structure–function relationship over different catalysts was highlighted, molecular sieve, precious metal, transition ion liquid. In addition, future challenge regarding simultaneous treatment mixed plastics also summarized, along with copyrolysis waste biomass. As such, underscores sustainable scalable solutions for polyolefin upcycling, which may shed light upon industrial application resources.

Polyethylene Upcycling to Liquid Alkanes in Molten Salts under Neat and External Hydrogen Source-Free Conditions

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: April 7, 2025

Development of facile approaches to convert plastic waste into liquid fuels under neat conditions is highly desired but challenging, particularly without noble metal catalysts and an external hydrogen source. Herein, efficient selective polyethylene-to-gasoline oil (branched C6-C12 alkanes) conversion was achieved mild (<170 °C) using commercially available AlCl3-containing molten salts as reaction media provide catalytic sites (no extra solvents, additives, or feeding). The high efficiency selectivity ensured by the abundant active Al with strong Lewis acidity (comparable type in acidic zeolite) ionic nature stabilize carbenium intermediates. Dynamic genesis elucidated via time-resolved K-edge soft X-ray 27Al NMR, confirming tricoordinated Al3+ its coordination as-generated alkene/aromatic formation polyethylene chain variation illustrated inelastic neutron scattering (INS) isotope-labeling experiment. Theoretical simulations further demonstrated successive hydride abstraction, β-scission, isomerization, internal transfer pathway AlCl3 sites. This system can achieve robust, densely assembled, molecular weight model compounds alkane products diesel range.
