As a promising fresh water harvesting technology, interfacial
solar
steam generation has attracted growing interest. Efficient solar absorption
and long-term operational performance are critical requirements of
this technology. However, developing robust evaporators to promote
practical applications under extreme conditions is still a grand
challenge. Herein, we propose a light-assisted strategy to in situ
prepare a Ti3C2Tx MXene anchored structure (MXAS) for enhanced solar evaporation with
superior mechanical properties (compressive strength of 78.47 MPa,
which can withstand a pressure of 3.92 × 106 times
its own weight). Light irradiation enlarges the interlayer spacing
of MXene and improves the solar absorption capability. Under one sun,
the three-dimensional MXAS evaporator exhibits a steam generation
rate of 2.48 kg m–2 h–1and an
evaporation efficiency of 89.3%, and it demonstrates long-term durability
when testing in seawater. This strategy provides valuable insights
into the potential application of a high-performance water evaporation
system.
