Flake-like CuO nanostructure coated on flame treated eucalyptus wood evaporator for efficient solar steam generation at outdoor conditions

Currently, interfacial solar steam generation (ISSG) in desalinating water becomes very popular for obtaining puri ed water from polluted water. But, nding a suitable evaporator with low cost and high-e cient is the challenging task for researchers. In this work, we introduce natural bamboo wood that acts as an interfacial evaporator for obtaining puri ed water. Four different wood evaporators namely, at wood (BW-FW), two-cut grooved wood (BW-2G), four-cut grooved wood (BW-4G) and four-cut grooved with Co 3 O 4 coated wood (BW-4g/Co 3 O 4 ) are used to study the mass loss (ML), evaporation rate (ER) and evaporation e ciency (EY). From the observations, BW-4g/Co 3 O 4 gives an admirable ML, ER and EY is 4.4 g, 3.366 kg/m 2 h and 91.34 % under 1 sun illumination for 60 min. Also, it is kept at open atmosphere conditions under natural sun illuminations.It achieves 17.8g of ML, 1.92 kg m -2 h -1 of ER and 76 % of EY respectively under 604.762 W/m 2 solar illumination for 8 h. We suggest the following are the reasons for the observed results: (i) the presence of grooves increase the exposing area for solar illuminations (ii) the super hydrophilicity nature of wood gives continuous replenishment of water from the bottom to the evaporative surface (iii) the excellent salt rejection property of wood is employed for continuous water transportation without salt accumulations. As a result, the salinity of the condensed water is measured that comes under WHO standards. Consequently, it gives better dye removal from polluted water.
