Salt-tolerant and low-cost flame-treated aerogel for continuously efficient solar steam generation

A Stable Bilayer Polypyrrole‐Sorghum Straw Evaporator for Efficient Solar Steam Generation and Desalination

“…Above phenomenon may be attributed to the fact that PPy-SS has penetrating water transport channels and good hydrophilicity, which allows continuous supply of water to the photothermal surface, and consequently promotes to the salt dissolution into seawater through the water transport channels under the action of diffusion and convection caused by different salt concentration. [33,71] The seawater desalination performance of evaporator plays a decisive role in its practical application of evaporators. Seawater used in this work was taken from the East China Sea.…”

“…You et al. [ 33 ] developed a cellulose aerogel from natural wood to act as a solar interfacial evaporator, which can achieve an evaporation rate of 1.40 kg m −2 h −1 , corresponding to an evaporation efficiency of 83.4% under 1 Sun. Liu et al.…”

“…[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] For example, Dong et al [32] developed reed leaves inspired silica nanofibrous aerogel interfacial evaporator that achieves an evaporation rate of 1.25 kg m −2 h −1 under 1 Sun. You et al [33] developed a cellulose aerogel from natural wood to act as a solar interfacial evaporator, which can achieve an evaporation rate of 1.40 kg m −2 h −1 , corresponding to an evaporation efficiency of 83.4% under 1 Sun. Liu et al [34] developed a carbonized chitosan aerogel interfacial evaporator that achieves an evaporation rate of about 1.76 kg m −2 h −1 and an evaporation efficiency of about 91.0% under 1 Sun.Among solar interfacial evaporators, interfacial evaporators with bilayer structure are one of the typical types.…”

Solar-driven interfacial evaporation for water treatment: advanced research progress and challenges

“…[1][2][3] In recent years, increasing types of photothermal materials (PMs) have been designed based on interfacial evaporation, mainly including natural products, 4-10 polymers, [11][12][13][14][15] carbon materials, [16][17][18][19][20][21] and semiconductors. [22][23][24][25][26][27] Besides, the functions of the developed PMs are becoming increasingly comprehensive, mainly covering long-term salt resistance, 6,[28][29][30][31][32] self-cleaning [33][34][35][36][37] and collaborative power generation. [38][39][40][41][42][43][44] Collaborative power generation occurs due to the upward ow of water caused by solar-driven PMs, creating concentration and temperature differences between the interface and the water body, thus generating electricity and water vapor simultaneously.…”

Fabrication of a Highly Efficient Wood-Based Solar Interfacial Evaporator with Self-Desalting and Sterilization Performance

“…The natural-derived porous wood has become an ideal candidate for the construction of a water transport substrate for SIE . The natural hydrophilicity and low thermal conductivity of wood could improve the water transport performance and reduce heat loss. , So far, developments of wood-based SIE are mainly focused on strategies based on surface modifications with various photothermal materials including conjugated organic polymers, semiconductors, plasmonic nanomaterials, , wood carbonization, − and carbon-based materials. − As a narrow band gap (0.3 eV) semiconductor with a full spectral range for utilizing solar energy, nickel disulfide (NiS 2 ) has been demonstrated as a promising nanomaterial for constructing SIE photothermal modules. , Lignin also shows good photothermal conversion as a natural polymer, which was attributed to π–π stacking of lignin molecules . However, the synthesis of photothermal materials often suffers from the tedious steps and harsh conditions.…”
