A magnetic field induced photothermal evaporator assembled by
carbon-coated Fe3O4(Fe3O4@C) nanoparticles, which revealed
the adjustable surface structure corresponding to the relative distance
to magnet. The optimized evaporator assembled by
Fe3O4@C showed a uniform spiny surface
contributing to an obvious improvement on evaporation rate under
illumination and lower performance degradation in long-term
desalination.
