Biomimetic Dual Absorption–Adsorption Networked MXene Aerogel-Pump for Integrated Water Harvesting and Power Generation System

ACS Nano, Journal Year: 2024, Volume and Issue: 18(5), P. 4376 - 4387

Published: Jan. 25, 2024

Harvesting atmospheric water and converting it into electricity play vital roles in advancing next-generation energy conversion systems. However, the current harvester systems suffer from a weak capture ability poor recyclability due to high diffusion barriers low sorption kinetics, which significantly limit their practical application. Herein, we drew inspiration natural "Pump effect" observed wood successfully developed dual "absorption–adsorption" networked MXene aerogel (MAWH) through ice templating confining LiCl processes, thereby serving multiple purposes of clean production, passive dehumidification, power generation. The MAWH benefits H-bond network cellulose nanocrystals (absorption network) hygroscopic properties lithium chloride (adsorption network). Furthermore, its aligned wood-like channel structure efficiently eliminates nucleation near 3D network, resulting fast moisture absorption. demonstrates absorption 3.12 g g–1 at 90% relative humidity (RH), featuring rapid vapor transport rates durable cyclic performance. When compared with commercial desiccants such as 4A molecular sieve silica gel, can reduce RH 80% 20% within just 6 h. Most notably, our integrated MAWH-based harvesting–power generation system achieves voltage ∼0.12 V 77% RH, showcasing potential for These MAWHs are considered high-performance harvesters collection field.
