Investigation on the Low-Temperature Transformations of Poly(furfuryl alcohol) Deposited on MCM-41 [PDF]

, 2013
MCM-41-type mesoporous silica was used as a support for poly(furfuryl alcohol) deposition. This material was produced by precipitation–polycondensation of furfuryl alcohol (FA) in aqueous slurry of the SiO2 support followed by controlled partial ...

Inert Catalytic Sites Unlocked by Micropollutants for Rapid Water Decontamination with Near‐Complete Chemical Utilization

Advanced Materials, EarlyView.
Micropollutants can act as molecular triggers that activate a newly designed and chemically inert Fenton‐like PKU‐24 catalyst for on‐demand singlet oxygen generation from peroxymonosulfate (PMS), enabling nearly complete peroxide utilization and selective micropollutant removal from complex real‐world wastewater.

Carbon Membranes Prepared from Poly (Furfuryl Alcohol–Furfural) Precursors: Effect of FeCl₃ Additive

C, 2020
Thermosetting resins, such as poly (furfuryl alcohol), are efficient precursors for preparation of carbon membranes with molecular sieving properties. Polymerization of furfuryl alcohol is catalyzed by Bronsted or Lewis acids.

Cobalt Single‐Atom Catalysts for Ultrafast Sulfamethoxazole Degradation: Unveiling the Chloride‐Ion‐Enhanced Formation of Co(IV)=O

Advanced Science, EarlyView.
An atomically dispersed Co–N4 single‐atom catalyst rapidly activates peroxymonosulfate to remove the antibiotic sulfamethoxazole from water. Common ions have little impact, but chloride dramatically speeds degradation by promoting a high‐valent Co(IV) = O oxidant via in situ HOCl–catalyst electron transfer.
