Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Securing Water in a Changing Climate: A Transient Solar Desalination Model for the Sundarbans, Bangladesh

Energy Science &Engineering, EarlyView.
This graphical abstract presents a solar‐powered reverse osmosis (RO) system for the Sundarbans, Bangladesh. Mechanistic modeling reveals a critical seasonal mismatch: during the monsoon, feed water salinity peaks (24.8 ppt) while solar irradiance drops significantly.
