“…Solar assistant interface evaporation, where only solar energy input rather than electricity or fossil-based energy, is considered as the most economical technology to produce drinkable water from polluted and sea water to ease global water shortages [5][6][7]. Compared to numerous other available technologies, such as adsorbed treatment [8][9][10], reverse systems [11,12], multi-stage ash [13,14], tiny-fog collection [15][16][17] and traditional solar assistant bulk water heating steam generation [18], solar assistant interface evaporation technology can e ciently produce drinkable water owing to its excellent light trapping performance, unique interfacial localization way for energy utilization and an appropriate water supply system [19]. It is widely regarded that the sunlight trapping and photothermal conversion materials play a key role in solar interfacial evaporation systems [20,21].…”

As a promising technology, interfacial solar steam technology has been widely recognized as an effective way to solve the shortage of energy and water, especially in remote areas. Whole roll of toilet paper (TP) is composed of well orderly layer-by-layer paper which consisted by cellulose fiber. Here, a 3D solar steam generator which is prepared by carbonized TP with the help of high temperature carbonization and NaOH activated under inert atmosphere is firstly demonstrated with excellent fresh water production capacity. Thanks to the good ordered layered structure which consisted by porous carbon fiber, the evaporation speed of obtained evaporator is up to 3.37 kg m-2 h-1 under one sun (1000 W m-2) in laboratory, and the average value of 20.4 kg m−2 day−1 in a 20 consecutive days outdoor experiment for treatment of stimulate sea water, respectively. The demonstrated 3D evaporator for per square meter can meet the drinking water demand of more than 10 people. This work opens a promising approach for utilizing unique structure of commercialized available artificial materials and technologies to produce fresh water form seawater.

“…The challenges of energy and clean water scarcity, especially in the remote areas, are becoming a more and more serious issue and would severely influence on economic and society development 1 , 2 . Currently, many technologies have been proposed to solve these problems 3 – 5 , for instance reverse systems 6 , 7 , multi-stage flash 8 , 9 , adsorbed treatment 10 , tiny-fog collection 2 , 11 , 12 and interface solar assisted evaporation 13 , 14 , among which solar assisted evaporation is regarded as a promising strategy to address the fresh water scarcity by treating the seawater on account of its economically, easy operation, renewable energy sources, sustainability and environment friendliness 15 , 16 . The biggest advantage of interfacial evaporation is high solar energy utilizing efficiency which attributes to its excellent energy management by remarkably suppressing heat loss to bulk water via thermal insulation foam between the bulk water and work interface, and good water management enabled by hydrophilic properties of photo-thermals conversion materials 13 , 17 – 19 .…”

To date, various solar driven evaporation technologies have been developed for treatment of seawater and wastewater but with the threat from salt polluted and single treatment of seawater. Herein, we develop a multifunctional evaporator constructed by carbon fiber coated by quinoa cellulose nanosheet (CFQC) with outstanding self-cleaning performance and good purification property for treatment of organic and antibiotic polluted water. The resulting Zn-CFQC exhibits good light to thermal performance which can absorb about 86.95% lights in the range of UV–Vis–NIR (200–2500 nm); therefore, the wet and dry surface temperatures of Zn-CFQC are held at 62.1 and 124.3 °C respectively, and keep a speed of 3.2 kg m−2 h−1 for water evaporating under 1000 W m−2 illumination. Such good light-to-thermal capabilities can be mainly imputed to the unique surface microstructures of the carbon fiber which decorated by two-dimension cellulose and activated by ZnCl2. Additionally, Zn-CFQC shows good salt automatic-cleaning capability at night and corresponding mechanism has been simply elucidated according to the chemical potential theory. The method of treatment of carbon fiber opens a new way for commercial carbon fiber utilization of solar assisted water purification.
