Hydrogel‐Based Photothermal‐Catalytic Membrane for Efficient Cogeneration of Freshwater and Hydrogen in Membrane Distillation System

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 22, 2025

Abstract Photothermal‐catalytic (PTC) process is a promising way to produce freshwater and clean hydrogen by integrating solar‐driven desalination water splitting. However, efficient solar spectrum utilization coupled with effective mass thermal management poses key challenges in developing multifunctional PTC systems. Here, highly stable hydrogel membrane (CdS/MX‐HM) that incorporates MXene in‐situ generated CdS as the materials into customized vacuum distillation (VMD) setup demonstrated. The CdS/MXene composites utilize full spectrum, contributing photothermal ability serving co‐catalyst enhance photocatalytic performance, which are effectively integrated system. These functional immobilized within hydrophilic PVA/chitosan layer, creates supramolecular network provides excellent stability protection while offering an interface for processes. Supported hydrophobic PTFE substrate, system enables fast gas transfer permeate, completing dual‐function design. Through systematic optimization of structure operational parameters, PTC‐VMD achieves flux 1.63 kg m − 2 h ¹ production rate 3099 µmol −1 under one sun irradiation, demonstrating its potential sustainable solution water‐energy nexus challenge.
