A portable and reusable solar water distillation structure based on low cost ceramic materials is developed. The structure is made of ceramic fiber wool (CW) and titanium nitride nanoparticles (TiN NPs) that are chemically immobilized to the CW. When sunlight illuminates the structure, the TiN NPs absorb sunlight while unnecessary heating of the remaining water is suppressed by the CW. The CW effectively supply water by capillary force such that the TiN NPs are always kept close to the water surface. It yields a solar thermal conversion efficiency of more than 80% at 100 mW cm(-2) that is much more efficient than the conventional systems. Our structures can be used as eco-friendly and efficient solar water distillator.
