Published: Aug. 30, 2023

Abstract Recent research on wood‐based solar evaporators has made great progress and significant breakthroughs have been in using lignin as a photothermal material; however, the intensity change mechanism regarding conjugate structure of is almost never mentioned. This study innovatively proposes to explain changes that occur before after dissolution fabricates lignin/wood‐based evaporator (LWE) an all‐wood‐based material salt‐tolerant long‐term serviceability. Lignin serves not only for converting light energy into heat but also reinforcement evaporator's structural strength. Adding original balsa wood, increasing proportion intermediate water LWE, thereby lowering enthalpy evaporation. The optimized LWE with enhanced desalination capability, dye removal property, high stability exhibits full‐spectrum absorption about 83.6%, conversion efficiency 91.74%, evaporation 1.93 kg m −2 h −1 , which surpasses most evaporators. demonstrates materials can be used prepare excellent performance, providing new approach address freshwater depletion.

Orientational Bamboo Veneer Evaporator for Enhanced Interfacial Solar Steam Generation

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(8), P. 3331 - 3343

Published: Feb. 9, 2024

Given the green developments in interfacial solar steam generation (ISSG), a biobased evaporator with excellent photothermal conversion efficiency is urgently needed to address freshwater shortage. However, it still challenging that evaporators like wood and bamboo are underutilized due capillary actions different channel directions. Herein, we investigated structural properties of veneer for contrast analysis between transverse sections (BTR) tangential (BTA). The one-step torrefaction method was used improve optical absorption lignin 200–2500 nm band. Owing perpendicular design, BTR conducting straight energy loss bulk water restricts performance. BTA evaporator's parallel design micronano unit presents better management (surface temperature could reach 57.1 °C under 1 kW/m2 illumination), leading efficient evaporation performance (1.425 kg/m2 h). These findings contribute our cognition solar-driven transport suggest ISSG develop produce from seawater or sewage.

Unique suspension solar evaporator is one of the effective measures to address major bottleneck emerging interfacial evaporators, i.e., accumulation salts on surface. Yet, it remains a considerable challenge avoid substantial heat loss underwater. Herein, wood-based proposed with thermal convection structure that effectively balances contradiction between salt-resistance ability and loss. Benefitting from centralization due convection, such exhibits an excellent steam generation rate, which increases 1.23 1.63 kg m
