“…However, this process usually suffers form high concentration sunlight because of the large energy losses, which hinders the large‐scale productions. To enhance the energy conversion efficiency, a method constructing floating porous photo‐thermal materials at the air‐water interface has attracted extensive attentions . Similar to natural plant transpiration and human sweating system, the heat generated by absorbers can be effectively localized at the interface and facilitate the vapor production.…”

“…Similar to natural plant transpiration and human sweating system, the heat generated by absorbers can be effectively localized at the interface and facilitate the vapor production. In this case, the temperature of localized region is much higher than that of the bulk water, allowing to reduce the heat losses . Obviously, the efficiency of the solar evaporation system principally relies on the performance of light‐absorbing materials, which is a crucial factor throughout the process.…”

Solar steam generation is a potential approach for fresh water recycling, thus attracting increasing attention recently. To further promote water evaporation rate, some new materials need to be developed, such as plasmonic transition metal oxides. In this work, we report an oxygen‐defected molybdenum oxides hierarchical nanostructure (MoOx HNS) composed of ultrathin nanosheets with atomic‐level thickness, which is demonstrated as an efficient absorber for solar steam generation. Benefiting from broadband light absorption and special assembled architecture, the resulting MoOx HNS loaded on a PTFE membrane (MoOx HNS Membrane) exhibits excellent performance for boosting steam generation rate. Under 1 sun (1 kW m−2) illumination, the evaporation rate can reach at 1.255 kg m−2 h−1, with the energy conversion efficiency of 85.6%, which is one of the best performance compared with other desalination materials. Meanwhile, the MoOx HNS Membrane can achieve high‐performance seawater desalination in both laboratorial and outdoor conditions. The enhanced water evaporation performance can be attributed to the synergistic effects of the efficient solar‐to‐thermal conversion and the unique channel structure. This work expands the scope of investigated materials which can be applied in seawater desalination system.

“…As a transition from nanofluids to solid PTC materials, Wang et al utilized a self‐assembly process to create a free‐floating film of gold nanoparticles at the air–water interface that could pump the liquid to the open surface during liquid evaporation through capillary flow. Whereafter, Au‐dominated plasmonic metal and carbon solid PTC materials were widely researched for solar water evaporation . Most of them are double layer structured (DLS) composite materials consisting of a PTC layer and a functional layer with the properties of porosity, adiabaticity, and free‐floating to allow heat localization and continuous water supplement.…”

“…Most of them are double layer structured (DLS) composite materials consisting of a PTC layer and a functional layer with the properties of porosity, adiabaticity, and free‐floating to allow heat localization and continuous water supplement. For instances, Wang et al dispersed Au nanoparticles on the mixed cellulose ester (MCE) filter membrane for water evaporation. Zhou et al deposited Au nanoparticles on Al 2 O 3 nanoporous template to synthesize a plasmonic absorber for solar steam generation, which enabled not only efficient solar absorption but also significant local heating and continuous stream flow.…”

Hierarchical TiN nanotube mesh (HTNM) is prepared by calcining TiO2 nanotube mesh (TONM) in NH3 flow where the TONM is fabricated by electrochemical anodic oxidation of Ti mesh. Calcining temperature affects not only phase composition but also morphology of the HTNM, which further affects its optical absorption and solar water evaporation conversion efficiency (η). The η can reach to 85.36% under 2.5 kW m−2 simulated solar irradiation because HTNM efficiently utilizes solar light. Moreover, it can be reutilized because of its stabilities of the phase composition and nanostructure during the measurements of solar water evaporation performance.

Solar vapor generation is a facile and an efficient way for solar energy harvesting, which is applied to address the issue of fresh water extraction from sewage or brine. Several solar vapor generation devices have been developed in the past few years, but the low evaporation rate still remains as a challenge. In this work, a novel double-layer solar vapor generation device, named as Ag-PSS-AG/AG device, is reported. This device is based on the hierarchical composition of silver nanoparticles (Ag NPs) and poly (sodiump-styrenesulfonate) (PSS) decorated agarose gel (AG). The device reveals a synergetic effect of the two layers with high light-harvesting and watertransfer performance, respectively, leading to an ultrahigh vapor generation rate of 2.10 kg m −2 h −1 with a solar thermal efficiency of 92.8% under 1 sun illumination. This high evaporation rate is mainly owing to the powerful light-thermal conversion of Ag NPs as well as the outstanding water transfer capability of agarose hydrogel. Consequently, this device can be directly used for the purification of sewage and muddy water. It is also promising for applications in separation, humidity management, and others.NPs embedded in AG skeleton ensures the adequate transfer and full utilization of the converted heat energy. Therefore, the Ag-PSS-AG/AG device exhibits an ultrahigh vapor generation rate of 2.10 kg m −2 h −1 with a solar thermal efficiency of 92.8% under 1 sun illumination.
