“…Wang et al (2016b) studied photothermal CNT-based materials and reported a solar thermal conversion efficiency of as high as 82% with bilayered CNT-silica materials. Polymers such as polydopamine was pioneered as a biodegradable PTM (Jiang et al, 2017). Organic polymers such as polypyrrole (Zhang et al, 2015a), polyaniline (PANI) (Huang et al, 2015a), and poly(1,3,5hexahydro-1,3,5-triazine) (Chen et al, 2018) have been explored for their photothermal properties.…”

Among several active photothermal nanomaterials, tungsten-oxide-based materials have received considerable attention recently because of their ability to absorb near-infrared (NIR) light and their efficient light-to-heat conversion properties. In addition, tungsten-oxide-based materials have an unusual oxygen defect structure and strong local surface plasma resonance (LSPR), which offers strong photoabsorption in a broad wavelength range of the NIR region. In the past, several light-absorbing nanomaterials such as noble metals, polymeric materials, and other inorganic nanomaterials were of interest for their use in photothermal therapy for cancer treatment. In this study, we review the synthesis, properties, and applications of tungsten-oxide-based nanomaterials as a new type of photothermal material. The basic ideas behind photothermal nanomaterial development as well as the factors that influence their structural designs are also discussed in this study. In addition, recent progress in various fields such as NIR light-shielding, pyroelectric, water evaporation, photocatalysis, gas sensors, and energy-related applications for WO 3−x-and M x WO 3-based nanomaterials (including their hybrids) are highlighted. Finally, this review presents promising insights into this rapidly growing field that may inspire additional research leading to practical applications.

“…This indicated that the CNFAs effectively suppressed light reflection and improved absorbance, which is superior to most of the current reports (Figure 4c). [15,[33][34][35][36][37][38][39] High light absorption laid a sound foundation for high photothermal conversion. The temperature distribution and change of CNFAs under light irradiation from a solar simulating source were monitored using an infrared (IR) thermal imager.…”

Cellular Structured CNTs@SiO₂ Nanofibrous Aerogels with Vertically Aligned Vessels for Salt‐Resistant Solar Desalination

et al. 2020

The emerging solar desalination technology is considered as one of the most promising strategies to ensure water security. However, with the proceeding of solar desalination, salt crystallization on the surface of solar evaporators caused by increasing salinity of seawater will result in a decrease in the evaporation rate. Thus, it is still challenging to fabricate solar evaporators with superior salt resistance. In this work, elastic ceramic‐based nanofibrous aerogels with a cellular architecture are fabricated by the combination of electrospinning and fiber freeze‐shaping technologies, which are composed of vertically aligned vessels and porous vessel walls. Under the action of convection and diffusion promoted by this unique cellular architecture, the aerogels exhibit a superior salt‐resistance without any salt crystals on the surface of aerogels even in 20% brine and under 6‐sun irradiation. Moreover, by virtue of the synergistic effect of the promising structure and light absorbance of carbon nanotubes, aerogels possess a high light absorbance of up to 98% and excellent evaporation performance achieving 1.50 kg m−2 h−1 under 1‐sun irradiation. This work may provide a fascinating avenue for the desalination of seawater in a salt‐resistance and efficient manner.

“…As a result, Chinese black ink as the solar absorber coating was required to be further stabilized by atomic layer deposition (ALD) technique to improve the interfacial adhesion to the substrate and prevent the ink dispersing into the water. [71] Beyond above report, a series of PDA coatings have been developed as the photothermal agents for various applications, including photothermal therapy, [101] photothermal antibacteria, [102] photothermal-assisted MD, [103] photo thermalassisted water evaporation, [104,105] and photothermal-assisted crude oil cleanup. [97][98][99] It is well known that the structure of PDA is similar to eumelanin in organism, and thus it would enable PDA coating with excellent light absorption ability.…”

Producing affordable freshwater has been considered as a great societal challenge, and most conventional desalination technologies are usually accompanied with large energy consumption and thus struggle with the trade‐off between water and energy, i.e., the water–energy nexus. In recent decades, the fast development of state‐of‐the‐art photothermal materials has injected new vitality into the field of freshwater production, which can effectively harness abundant and clean solar energy via the photothermal effect to fulfill the blue dream of low‐energy water purification/harvesting, so as to reconcile the water–energy nexus. Driven by the opportunities offered by photothermal materials, tremendous effort has been made to exploit diverse photothermal‐assisted water purification/harvesting technologies. At this stage, it is imperative and important to review the recent progress and shed light on the future trend in this multidisciplinary field. Here, a brief introduction of the fundamental mechanism and design principle of photothermal materials is presented, and the emerging photothermal applications such as photothermal‐assisted water evaporation, photothermal‐assisted membrane distillation, photothermal‐assisted crude oil cleanup, photothermal‐enhanced photocatalysis, and photothermal‐assisted water harvesting from air are summarized. Finally, the unsolved challenges and future perspectives in this field are emphasized. It is envisioned that this work will help arouse future research efforts to boost the development of solar‐driven low‐energy water purification/harvesting.
