Pore-Hierarchy Engineering of Cigarette Butt Waste Into Porous Carbon for CO₂ Adsorption. [PDF]

Glob Chall
Whole cigarette‐butt waste is converted into porous carbon by carbonization and Na2CO3 activation. Varying Na2CO3 loading regulates pore development and CO2 uptake, with WCB‐83 adsorbing 3.0 mmol g−1 at 273 K and 1 bar. The study links waste valorization with pore‐structure control in carbon adsorbents. ABSTRACT Cigarette butts are a persistent plastic‐

Crosslinking of Linear Polyimines Into Aminal-Linked Porous Organic Polymers for C₂ Hydrocarbon/Methane Separation. [PDF]

Angew Chem Int Ed Engl
Crosslinking of linear polyimines with aromatic diamines via nucleophilic addition converts nonporous polyimine precursors into aminal‐linked porous networks, offering a new strategy for synthesizing porous organic polymers. The resulting materials exhibit high C2 hydrocarbon adsorption capacity, excellent selectivity over CH4, and durable cyclic ...
