From technical feasibility to institutional misalignment: stakeholder insights into PVC circularity across the value chain

Purpose The global polyvinyl chloride (PVC) market continues to expand, making PVC one of the most widely produced and utilised plastics worldwide. Despite its versatility, a substantial proportion of PVC waste is landfilled, generating significant environmental and public health...

Geometry‐Controlled Cooperativity at Binuclear Fe 2 –N 6 Sites Enables Selective Fe IV ═OGeneration for Durable Fenton‐Like Oxidation

ABSTRACT Single atom catalysts (SACs) are emerging as a promising platform for Fenton‐like water purification; however, their practical deployment is often constrained by the trade‐off between high intrinsic activity and long‐term stability. Here, we construct an N‐bridged binucl...

Spin Coupled FeCo Dual‐Atom Sites Direct Selective Ozone Activation for Hypersaline Wastewater Purification

ABSTRACT Heterogeneous catalytic ozonation represents a powerful process for eliminating refractory organic contaminants from hypersaline wastewater, yet its application is restricted by two critical bottlenecks: inefficient ozone activation and lack of control over on‐demand rea...

Engineering N-site isomerism in donor-acceptor covalent organic frameworks for efficient Fenton-like water purification

Abstract Covalent organic frameworks (COFs) have emerged as promising candidates for singlet oxygen ( 1 O 2 ) generation via peroxymonosulfate (PMS) activation, yet their structure-property-activity relationships remain poorly understood. Herein, three constitutionally isomeric d...
