Jute stick derived self-regenerating sustainable solar evaporators with different salt mitigation mechanisms for highly efficient solar desalination

Abstract

The accumulation of salt crystals on the solar-absorbing surface of the evaporator is one of the main challenges associated with solar desalination. To solve this problem, sustainable evaporators with diverse...

Bifunctional Solar Evaporator with Co/N-Doped Graphene Oxide for Synergistic Steam Generation and Organic Pollutant Degradation

“…As a wide range of refractory organic contaminants was present in the actual water environment, the catalytic efficiency of the CNG-800/MF evaporator was investigated by examining organic pollutants (Figures b, S13). The CNG-800/MF evaporator completely removed SMX within 40 min and RhB and MB within 60 min, and demonstrated removal efficiencies of 90.3% for TC, 95.3% for CBZ, and 83.1% for ATZ within 60 min. These results confirmed that the as-designed CNG-800/MF evaporator possessed excellent universal applicability in the treatment process of a complex water system.…”

Recent Advancement in Solar‐Driven Interfacial Steam Generation for Desalination: A State‐of‐the‐Art Review

“…Shi et al [ 137 ] fabricated conjugated microporous polymer sponges by embedding porphyrin/aniline‐based polymers on PU sponges by dip coating technique (as shown in Figure 6b (i–v)) which shows seawater 1.33 kg m −2 h −1 evaporation rate and 87% PTC efficiency. Ivan et al [ 138 ] fabricated a 3D solar evaporator and obtained a 1.4 kg m −2 h −1 evaporation rate and 79% PTC efficiency. The PU sponge acted as a support component to keep the evaporator floating on water and to facilitate faster water conveyance to the top surface of the absorber.…”

“…Generally, the naked eyes observe the salt cleaning process in such cases. To enhance the visibility of salt crystals, Ivan et al [ 138 ] dried their solar evaporator using a drying oven after evaporating 10 wt% brine water solution and put it again on the 10 wt% brine water under no light condition. After 5 h, no salt crystal was observed on the evaporator surface as the wastepaper‐derived egg tray‐based solar evaporator dissolved the salt crystals.…”

Inspired by Plant Transpiration: Fabrication of a Unique Micro–Nano-Structured Janus Evaporator Using Waste Cotton Fabric for Enhanced Efficiency and Salt Resistance

“…35 There are also solar evaporators with mechanisms that induce the diffusion and return of salt ions. 36 However, the specific structure of the hydrogel evaporator makes it difficult to achieve excellent salt resistance.…”

“…The intermediate water between bound water and free water exists in a delicate interaction state, allowing vaporization with less energy. − Liu et al overcame the challenge of balancing heat management and salt resistance by using a three-dimensional hydrogel evaporator with a vertical radiation container . There are also solar evaporators with mechanisms that induce the diffusion and return of salt ions . However, the specific structure of the hydrogel evaporator makes it difficult to achieve excellent salt resistance.…”
