“…The carbon black–coated foam particles are used as solar-heated floaters for evaporation. Carbon black has been proven to effectively convert solar power into heat, and the foam core prevents the thermal conduction between the heated carbon black and water ( 32 , 33 ). As shown in Fig.…”

Significance Adjusting the floating states when objects float on water shows great potential for assembly, mineral flotation, nanostructured construction, and floating robot design, but the real-time regulation of floating states is challenging. Inspired by the different floating states of a falling fruit, we propose a facile strategy to transform the object between different floating states based on a three-segment three-phase contact line evolution. In addition, the potential of floating state transformation in solar-powered water evaporation, interface catalysis, and drug delivery is demonstrated. These findings provide insights into floating regulation and show great potential for floating-related applications.

“…Carbon-based materials have attracted much attention for their great potential in the solar-driven evaporation field, owing to their extraordinary light absorption in the visible spectrum, low-cost and great abundance [13]. Carbon-based materials, such as carbon black [30,31], carbon nanotube (CNT) [32], reduced graphene oxide (rGO) [33,34], and bio-char [23,35,36], have been investigated to be applied photothermal conversion materials in the solar-driven evaporation field. As the sunlight irradiates the carbon-based materials, an electronic transition can be excited by matchable incident light; an electron-phonon coupling can induce the transfer of energy from the excited electrons to the atomic lattice vibration due to the electronic transition, leading to carbon-based materials generating heat [37].…”

With the development of the industry, water pollution and shortage have become serious global problems. Owing to the abundance of seawater storage on earth, efficient solar-driven evaporation is a promising approach to relieve the freshwater shortage. The solar-driven evaporation has attracted tremendous attention due to its potential application in the seawater desalination and wastewater treatment fields. Also, the solar-driven evaporation efficiency can be enhanced by designing both solar absorbers and structures. Up to now, many strategies have been explored to achieve high solar-driven evaporation efficiency, mainly including the selection of photothermal conversion materials and structure optimization. In this review, the solar absorbers, structural designs, and energy management are proposed as the keys for high performance solar-driven evaporation systems. We report four kinds of solar absorbers based on different photothermal conversion mechanisms, substrate structure designs, and energy management methods for the purpose to achieve high conversion efficiency. And we also systematically investigate the available salt-rejections strategies for seawater desalination. This review aims to summarize the current development of efficient solar-driven evaporation systems and provide insights into the photothermal conversion materials, structural designs, and energy management. Finally, we propose the perspectives of the salt-rejection technologies for seawater desalination.
