A high-efficiency solar desalination evaporator composite of corn stalk, Mcnts and TiO2: ultra-fast capillary water moisture transportation and porous bio-tissue multi-layer filtration

Natural low-cost corn stalks as high-efficiency solar steam generators is developed, and the constructed solar evaporation device can generate 4.3–5.8 kg m⁻² on the sunny days and 3.0–3.9 kg m⁻² on the cloudy days.
