An upcycled wood sponge adsorbent for drinking water purification by solar steam generation

Abstract

The shortage of freshwater resources caused by heavy metal pollution is an acute global issue. Herein, a novel nanoplatform was fabricated by hydrothermal deposition of 3D-MoS2 nanospheres onto biocompatible wood...

Constructing A Solar Evaporator by Stacking Exhausted Wood Sponges for Freshwater Generation and Fertilizer Recovery

“…BET results indicate that the calculated surface area of the PGWS was 48.106 m 2 g −1 and the average pore size of PGWS was 2.384 nm. Previous results indicate that the specific surface area of WS is 49.557 m 2 g −1 [11] . Evidently, the filling of PG in the channels does not result in a large change of the specific surface area.…”

“…Previous results indicate that the specific surface area of WS is 49.557 m 2 g À 1 . [11] Evidently, the filling of PG in the channels does not result in a large change of the specific surface area. Meanwhile, the mesopores structure of PGWS plays an important role in the adsorption ability for metal ions.…”

“…[10] In our previous studies, wood sponge-based materials were synthesized for metal ion adsorption and subsequent solar steam generation, which not only reduces costs but also helps with resource utilization. [11] Therefore, functionalized PPy based wood sponge could provide a new platform for metal ion removal where the saturated adsorbents are able to be upcycled for photothermal evaporation.…”

“…Additionally, PPy has gained widespread attention as an adsorbent material due to its characteristic features including the possibility for easy chemical modification of its properties [10] . In our previous studies, wood sponge‐based materials were synthesized for metal ion adsorption and subsequent solar steam generation, which not only reduces costs but also helps with resource utilization [11] . Therefore, functionalized PPy based wood sponge could provide a new platform for metal ion removal where the saturated adsorbents are able to be upcycled for photothermal evaporation.…”

Reusable Floating Spherical Hydrogel Evaporator for Solar Desalination with Salt Mitigation and Contaminant Elimination

“…The scarcity of fresh drinking water is a pervasive global problem affecting people worldwide. , Desalination is considered as an effective, sustainable approach to generate fresh water from seawater and brackish water. , Current desalination technologies are based on reverse osmosis, multistage flash distillation, and electrodialysis, which are expensive. − Solar-induced desalination treatment is a cost-effective as well as eco-friendly approach that uses an interfacial evaporation system to isolate the evaporation interface from bulk water. Heat localization is conducted at the air–water interface to avoid the conduction of heat to the entire water mass and achieve efficient evaporation. ,, The use of various photothermal materials having high light absorption and light-to-heat conversion efficiency concentrates heat on the evaporation surface, which accelerates water transport that balances the evaporation rate. − …”
