Pressing need goes ahead for accessing freshwater in insufficient supply countries and regions,which will become a restrictive factor for human development and production.In recent years,solar-driven water evaporation(SDWE)systems have attracted increasing attention for their specialty in no consume con-ventional energy,pollution-free,and the high purity of fresh water.In particular,carbon-based pho-tothermal conversion materials are preferred light-absorbing material for SDWE systems because of their wide range of spectrum absorption and high photothermal conversion efficiency based on super-conjugate effect.Until now,many carbon-based SDWE systems have been reported,and various struc-tures emerged and were designed to enhance light absorption,optimize heat management,and improve the efficient water transport path.In this review,we attempt to give a comprehensive summary and dis-cussions of structure progress of the carbon-based SDWE systems and their working mechanisms,includ-ing carbon nanoparticles systems,single-layer photothermal membrane systems,bi-layer structural photothermal systems,porous carbon-based materials systems,and three dimensional(3D)systems.In these systems,the latest 3D systems can expand the light path by allowing light to be reflected mul-tiple times in the microcavity to increase the light absorption rate,and its large heat exchange area can prompt more water to evaporate,which makes them the promising application foreground.We hope our review can spark the probing of underlying principles and inspiring design strategies of these carbon-based SDWE systems,and further guide device optimizations,eventually promoting in extensive practi-cal applications in the future.
