Triboelectric nanogenerators are promising green electrocatalytic alternative energy sources; however, their low current density renders practical applications challenging. Herein, a self‐generating electricity mode based on a droplet friction strategy that significantly mitigates membrane fouling while facilitating the contact of oxidizing substan...

Nanofiltration (NF) membranes with exceptional ion selectivity and permeability are needed for the recovery of lithium from waste lithium‐ion batteries. Herein, inspired by the homogeneous microchannels in the skeletal structure of glass sponges, an innovative biomimetic sponge‐like sub‐nanostructured NF membrane was designed using an alkali‐induce...

Waterborne organic pollutants pose significant threats to ecosystems and the health of billions worldwide, presenting a pressing global challenge. Advanced oxidation processes (AOPs) offer promise for efficient wastewater treatment, yet the efficacy and the reliability of current environmental catalysts hinder their widespread adoption. This study...

Water reuse is an effective way to solve the issues of current wastewater increments and water resource scarcity. Ultrafiltration, a promising method for water reuse, has the characteristics of low energy consumption, easy operation, and high adaptability to coupling with other water treatment processes. However, emerging organic contaminants (EOCs...

Over the last decades, ultrafiltration (UF) has been and will continue to play an important role in the Chinese drinking water industry. The hybrid membrane processes have been emerging as promising alternatives to traditional treatment processes. This review paper offers a thorough overview of the current status of UF technology in the drinking wa...

To achieve excellent activation efficiency of peroxymonosulfate (PMS), this work prepared a biochar-supported CuO (CuO@BC) catalyst, and the CuO@BC/PMS system was proposed to remove the organic matter in natural surface water and reduce the fouling of ultrafiltration membrane. The successful synthesis of CuO@BC was demonstrated through characteriza...

A photocatalytic membrane coated with α-Fe2O3/Fe3O4 nanoparticles has been developed to address the challenges of membrane fouling and organic removal in the treatment of natural surface water. The photocatalytic and filtration properties of the membranes were investigated through a variety of methods. The successful preparation of iron oxide was c...

This study aimed at investigating the removal performance of the gravity-driven membrane (GDM) system in treating the heavy metals-containing secondary effluent, as well as evaluating the respective roles of Fe and Mn addition on the removal of heavy metals. GDM process with the formation of biocake layer exerted effective removals of Cr, Pb and Cd...
