Facile synthesis of hierarchical SnSe nanosheets–hydrogel evaporators for sustainable solar-powered desalination

Abstract

In constrast to demand for freshwater that increases continuously due to population growth and economic growth, the availability of freshwater resources decreases rapidly due to environmental pollution and climate change....

A solar-powered interfacial evaporation system based on MoS2-decorated magnetic phase-change microcapsules for sustainable seawater desalination

“…7h). 31–37 In addition, the evaporation rate of the MoS 2 -MEPCM evaporator is proportional to the solar illumination intensity, and its evaporation efficiency increases from 93.45% to 96.69% when the solar illumination intensity is increased from 0.5 to 3.0 kW m −2 (Fig. 7i).…”

Piezoionic SnSe Nanosheets‐Double Network Hydrogel for Self‐Powered Strain Sensing and Energy Harvesting

“…An important finding in our previous work is that the hydrogels containing SnSe NSs had smaller pore sizes, [ 17 ] which may lead to better mechanical properties. As a sensing material, the structure of the material needs to be uniform; therefore, we chose the photo‐induced hydrogel polymerization method to reduce preparation time and avoid the Rayleigh‐Bénard effect.…”

Conversion of Hazardous Diesel Soot Particles into a Novel Highly Efficient 3D Hydrogel for Solar Desalination and Wastewater Purification

“…Heat localization and water transportation also play a significant role in ISSG performance. , Recently, the 3D structure of photothermal solar absorber have gained large traction in this regard owing to their intricate design that enhance heat localization at the air–water interface. , In addition, the modifications in water channels and environmental heating due to increased side surface area have led to the superior SSG performance in 3D hydrogels compared to 2D ones. − 3D structures like hydrogels are the recent evolution in ISSG-based solar desalination. − The 3D hydrogel composed of crosslinked polymer networks have several advantages in ISSG owing to their tunable physicochemical properties. , The presence of hydrophilic functional groups attached to the polymeric networks makes it extremely hydrophilic and water absorbent. Polyvinyl alcohol (PVA) is a common polymer utilized for ISSG because of its high hydrophilicity, non-toxicity, low cost, and facile fabrication. − The water activation state in PVA hydrogels can also be easily tuned by altering the polymer composition and crosslinkers. , Thus, PVA hydrogels are one of the ideal materials for ISSG.…”
