Non-metallic iodine single-atom catalysts with optimized electronic structures for efficient Fenton-like reactions.

In this study, we introduce a highly effective non-metallic iodine single-atom catalyst (SAC), referred to as I-NC, which is strategically confined within a nitrogen-doped carbon (NC) scaffold. This configuration features a distinctive C-I coordination that optimizes the electronic structure of the nitrogen-adjacent carbon sites. As a result, this arrangement enhances electron transfer from peroxymonosulfate (PMS) to the active sites, particularly the electron-deficient carbon.

Macro-constructing zeolitic imidazole frameworks functionalized sponge for enhanced removal of heavy metals: The significance of morphology and structure modulation.

Rational synthesis of metal-organic frameworks (MOFs) via structural and morphology engineering are fundamental for enhanced heavy metal removal. Beyond tuning intrinsic characteristics, it is essential to address inseparability and instability issues of MOFs to fulfill the practical applications. Herein, we successfully constructed macroscopic zeolitic imidazole frameworks-functionalized melamine sponge (MS@ZIF, x represents the ultrasonication duration) using a facile dip-coating method.

Defect-rich porous carbon with anti-interference capability for adsorption of bisphenol A via long-range hydrophobic interaction synergized with short-range dispersion force.

Wastewater features-directed design of an adsorbent is promising but challenging strategy for sustainable remediation of actual bisphenol A (BPA)-polluted water. Herein, we report that the discarded cigarette butt-derived porous carbon (AC-800) exhibit high capacity (865 mg/g), rapid reaction rate (186.9 mg/g/min) and outstanding durability for adsorption of BPA.
