Solar Steam Generation

The study of ideal absorbers, which can efficiently absorb light over a broad range of wavelengths, is of fundamental importance, as well as critical for many applications from solar steam generation and thermophotovoltaics to light/thermal detectors. As a result of recent advances in plasmonics, plasmonic absorbers have attracted a lot of attention. However, the performance and scalability of these absorbers, predominantly fabricated by the top-down approach, need to be further improved to enable widespread applications. We report a plasmonic absorber which can enable an average measured absorbance of ~99% across the wavelengths from 400 nm to 10 μm, the most efficient and broadband plasmonic absorber reported to date. The absorber is fabricated through self-assembly of metallic nanoparticles onto a nanoporous template by a one-step deposition process. Because of its efficient light absorption, strong field enhancement, and porous structures, which together enable not only efficient solar absorption but also significant local heating and continuous stream flow, plasmonic absorber–based solar steam generation has over 90% efficiency under solar irradiation of only 4-sun intensity (4 kW m−2). The pronounced light absorption effect coupled with the high-throughput self-assembly process could lead toward large-scale manufacturing of other nanophotonic structures and devices.

High Evaporation Rate

Utilizing solar energy to generate clean water by interface solar steam generation is considered to be a promising strategy to address the challenge of <a></a><a>water shortage globally.</a> However, <a></a><a>high evaporation rate and long-term sustainability have rarely been achieved simultaneously</a>, due to salt accumulation, discontinuous water supply and insufficient photothermal conversion. Herein, we demonstrate that a three-dimensional nanofibrous aerogel (3D NA) with Janus layers enables floating on the surface water by hydrophobic layer and continues pumping water by hydrophilic layer and interconnected porous structure. <a>More notably, an </a><a></a><a>aggregation-induced emission (AIE)</a> photothermal molecule is doped into nanofibers for the first time, which was endowed with superior capacity of transferring solar energy into heat. Combining these unique benefits, the presented 3D NA exhibits extremely high evaporation rate (1.99 kg m-2 h-1) and solar-to-vapor conversion efficiency (89%) under irradiation of 1 sun. Besides, there is no significant change in evaporation performance after 21 cycles in the case of seawater treatment, suggesting that the designed 3D NA possess sustainable stability and self-cleaning function to restrain salt deposition. With highly efficient evaporation rate and long-term sustainable solar steam generation, such 3D NA can offer new strategy for desalination and sewage treatment.
