Abstract Clean‐water harvesting through solar interfacial evaporation technology has recently emerged as a strategy for resolving global water scarcity. In this study, rapid carbon‐dioxide‐laser‐induced carbonization and facile ice‐templating is employed to construct cellulose‐based evaporator bearing hybrid multi‐layer micro‐/nano‐architecture (i.e., laser‐induced carbon (LC) nanostructure cellulose aerogel (CA) nano/microstructure). The LC exhibits light‐absorbing/photothermal nanoporous structure that offers high light absorption multiple scattering. Additionally, the CA numerous nanopores unidirectional microchannels facilitate transport via capillary action. This LC/CA enabled vapor generation with an average rate (ν) of 1.62 kg m −2 h −1 efficiency (η) 66.6%. To further enhance performance, polydimethylsiloxane (PDMS) layer coated onto side increase its floatability in simulated water; ν η PDMS‐coated (LC/CA/PDMS) increased 1.9 83.8%, respectively. LC/CA/PDMS exhibited value 1.68 seawater, originating from excellent resistance salt accumulation self‐cleaning ability. Furthermore, scalability fabrication well biodegradable properties.
