In situ iodine generation enables solution-phase polymerization of organic pollutants for continuous resource recovery from water
Abstract Oxidation-driven polymerization of organic pollutants offers a route to convert contaminants into value-added products and enable continuous resource recovery from water, but conventional heterogeneous processes are plagued by polymeric overlayers that foul catalyst surfaces and hinder long-term operation. Here, we realize solution-phase polymerization of 4-chlorophenol (4-CP) by relocating key bond-forming steps from catalyst interfaces into the bulk aqueous phase.
Scalable single-atom catalysts for cost-effective Fenton-like oxidation - Nature Water
Advanced oxidation processes (AOPs) empowered by single-atom catalysts (SACs) promise efficient water purification, but face the challenges of low catalyst yields, limited activity, and high costs of SACs. A novel salt-templating strategy enables mass production of SACs with precise multi-dimensional coordination and high metal loadings, potentially revolutionizing AOP technologies for water treatment.
Keto-anthraquinone covalent organic framework for H2O2 photosynthesis with oxygen and alkaline water - Nature Communications
Abstract Hydrogen peroxide photosynthesis suffers from insufficient catalytic activity due to the high energy barrier of hydrogen extraction from H2O. Herein, we report that mechanochemically synthesized keto-form anthraquinone covalent organic framework which is able to directly synthesize H2O2 (4784 μmol h−1 g−1 at λ > 400 nm) from oxygen and alkaline water (pH = 13) in the absence of any sacrificial reagents.
Rational design of dynamic fibre membrane for sustainable biofouling control - Nature Water
Abstract Current surface-controlled biofouling-based membrane technologies are retarded by short-run anti-biofouling performances. Dynamic fibre membrane, enriching the space and time of anti-biofouling agents acting on membrane, offers the potential to control biofouling in a continuous manner.
Breaking the Symmetry of Nitrogen‐Coordinated Single‐Atom Catalysts for Advanced Peroxymonosulfate Oxidation
Tuning the electronic distribution of the single-atom sites in single-atom catalysts (SACs) is crucial for unlocking their catalytic potential.
Comment on “Mechanistic Understanding of Superoxide Radical-Mediated Degradation of Perfluorocarboxylic Acids”
In their recent publication, Bai et al. (1) present a mechanistic exploration of the reactivity of a superoxide radical with perfluorocarboxylic acids (PFCAs). This is a valuable contribution that considers the role of solvation on superoxide reactivity and quantifies superoxide decay rates in the presence of PFCAs. However, PFCA degradation and defluorination data were not presented, and readers should be warned that superoxide by itself is not effective for PFOA degradation.
2D N-Doped Porous Carbon Derived from Polydopamine-Coated Graphitic Carbon Nitride for Efficient Nonradical Activation of Peroxymonosulfate
Nitrogen-doped carbon materials attract broad interest as catalysts for peroxymonosulfate (PMS) activation toward an efficient, nonradical advanced oxidation process. However, synthesis of N-rich carbocatalysts is challenging because of the thermal instability of desirable nitrogenous species (pyrrolic, pyridinic, and graphitic N). Furthermore, the relative importance of different nitrogenous configurations (and associated activation mechanisms) are unclear.
