Fabrication of Wood-Based Solar Interfacial Evaporators with Millimeter-Scale Artificial Channels and Study on Their Salt Resistance Performance
摘要
Abstract
Solar-driven interfacial evaporation technology possesses prominent application potential in seawater desalination by virtue of its merits including direct solar energy utilization and environmental friendliness.Nevertheless,this technology still suffers from limited photothermal conversion efficiency and deteriorated evaporation performance induced by salt crys-tallization under high-salinity conditions,which hinders its practical implementation.Herein,wood-based solar evaporators are fabricated by spraying sodium lignosulfonate(SLS)-modified hydroxylated multi-walled carbon nanotubes(OH-MWC-NTs)as photothermal materials onto lignin-removed balsa wood.Meanwhile,millimeter-scale artificial channels with var-ying quantities are constructed inside the wood substrate to optimize its salt-tolerant performance.The results showed that the SLS/OH-MWCNTs modified wood-based solar evaporator achieves a photothermal conversion efficiency of 91%with an evap-oration rate of 1.85 kg·m-2·h-1 under 1 kW·m-2 illumination,accompanied by outstanding cycling stability.The evapo-rator embedded with sixteen millimeter-scale artificial channels maintains a stable evaporation rate above 2.0 kg·m-2·h-1 during 6 h continuous evaporation in 10 wt%NaCl solution,and the removal efficiency of major ions in simulated seawater exceeds 99%.The composite of OH-MWCNTs and SLS enhances photothermal performance,while artificial channels ad-dress the salt crystallization issue.This strategy fully exploits the inherent structural advantages of wood.关键词
