Here we report highly efficient solar vapor generation using hollow-mesoporous plasmonic nanoshells, where the steam production is significantly enhanced by the extended active surface and the nearly neutral buoyancy. An energy-to-vapor conversion efficiency of 69% was measured under 10x solar irradiance. We also show clear evidence of direct vapor nucleation from the plasmonic structure without bulk heating.Engineering, Electrical & ElectronicNanoscience & NanotechnologyOpticsEngineeringScience & Technology - Other TopicsOpticsplasmonicsmesoporoushollownanoshellsolar-energynear-infraredvapor generationdesalinationtext::conference output::conference proceedings::conference paper
