Abstract
Au-loaded sulfur-impregnated charcoal was prepared from biomass waste bamboo and applied to solar absorbers for solar desalination. The evaporation rate of carbonaceous material was higher than that of raw bamboo, that of sulfur-impregnated carbon was higher than that of bamboo charcoal and commercial activated carbon due to sulfur impregnation, and that of Au-loaded sulfur-impregnated charcoal was the highest due to the Au particles on the charcoal surface. These results suggest that Au-loaded sulfur-impregnated charcoal has the potential to be used for solar evaporation.
