A vasculatural hydrogel combined with Prussian blue for solar-driven vapor generation

Abstract

Solar-driven clean water production presents unique merits of sustainability and environmental friendliness. Tremendous efforts have been devoted to the preparation of solar-driven vapor generators (SVGs) with timely water transport and/or...

“…In addition, doping of hydrophilic components such as Prussian blue or chitosan into the aerogel network not only facilitates the water supply but also reduces the enthalpy of water vaporization. [21,38,39] Based on this design, a high-water evaporation rate of 3.44 kg m -2 h -1 and energy efficiency of 95% are achieved under Xenon lamp source (Microsolar 300, Beijing Perfectlight) with 1 kW m -2 irradiation.

“…With this process, evaporation-based specific applications such as seawater desalination, sewage treatment, and energy transfer were presented. [17][18][19][20][21] The enhancement of solar evaporation efficiency can be well achieved by optimizing the alternative factors such as optical and energy utilization, water supply, and anti-fouling. It is considered that the solar evaporation system is holistically integrated from materials chosen and system design, and following specific applications, optimization with one of those factors alone cannot significantly influence the overall solar evaporation performance.…”

“…9b). 38 The wastewater disposal capability of the developed evaporator was also evaluated using a series of simulated industrial wastewater containing heavy metal ions (Pb 2+ , Cu 2+ , Zn 2+ , Ni 2+ , and Cd 2+ ) and organic dyes (methyl orange, rhodamine B, methyl blue, and methylene blue) as pollutants for purication. 39 Aer purication using the developed evaporator, there is a signicant decrease in the concentrations of Pb 2+ (from 868 to 0.54 mg L −1 ), Cu 2+ (from This journal is © The Royal Society of Chemistry 2022 3080 to 1.09 mg L −1 ), Zn 2+ (from 5070 to 0.89 mg L −1 ), Ni 2+ (from 4510 to 0.37 mg L −1 ), and Cd 2+ (from 2140 to 0.29 mg L −1 ) (Fig.…”
