Ferric tannate photothermal material for efficient water distillation

Abstract

Ferric tannate is used as a photothermal material and integrated with a polymer membrane by atomic layer deposition for solar water distillation.

Solar passive distiller with high productivity and Marangoni effect-driven salt rejection

“…accessible to more people), robust, efficient and stand-alone (where no moving parts are present) desalination technologies able to operate even in emergency conditions have been recently designed and studied in literature. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] The attention has been mainly focused on the study and design of new nano-structured materials and smart structures able to improve the solar-to-vapour conversion and the energy management. 13,[22][23][24][25][26][27][28][29] In 2018 some of the authors proposed a solar passive and multistage distiller 5 able to achieve performance beyond the thermodynamic limit of a single stage device, by recovering the latent heat of condensation.…”

A Gelation‐Stabilized Strategy toward Photothermal Architecture Design for Highly Efficient Solar Water Evaporation

“…[ 1,3,4 ] A variety of solar‐absorbing materials are developed and explored currently, such as low‐dimensional carbon nanomaterials, hydrogel‐based composites, covalent organic frameworks, organic/inorganic composite complex and plasmonic particles. [ 1,3,4,14–18 ] In comparison, it can be found that the materials with nearly 100% absorption of the full‐spectrum solar radiation did not achieve the same evaporation rate (ER) and some even exhibited a lower ER than those with the inferior absorbance. [ 15,19–24 ] This has been attributed to the differences of heat losses, particularly induced by conduction loss to the photothermal material itself.…”

Water treatment based on atomically engineered materials: Atomic layer deposition and beyond

“…Later, Zhang et al adopted the filtration/ALD coating method to realize black ferric tannate@TiO 2 coatings (Figure 11B). 83 The optimized as-fabricated membranes demonstrated a water evaporation rate of 0.441 kg À1 m À2 after 20 min operation. The evaporation efficiency in this case is ca.…”

“…Similarly, Zhang et al reported that black ferric tannate-based photothermal coating could be robustly adhered through stepwise filtration coating and ALD coating (Figure 6G). 83 There are few reports of similar multifunction integration cases during SIS processes, which is a ripe area for future investigation.…”
