英文摘要	Solar steam generation by heat localization has attracted much attention for its potential in the treatment of wastewater and seawater desalination. However, the preparation of a single-component solar receiver with low cost, simple preparation process, high mechanical strength and energy conversion efficiency is still a challenge. Herein, we report the preparation of kapok fiber-PPy aerogels with superwetting, porous structure, high light absorption, and high mechanical strength via polypyrrole modification of the Ca2+ crosslinked kapok fiber aerogels. The kapok fiber-PPy aerogels show three-dimensional structure with high porosity (94%), excellent light absorption (ca. 97%), low thermal conductivity (0.0241 W m(-1) k(-1)) and high mechanical strength (0.12 MPa under 75% of strain). As a solar steam generation device, a high energy conversion efficiency of 82.4% was achieved under 1 kW m(-2) illumination. The findings of this investigation may open a simple and novel route towards the fabrication of a low-cost a single-component biomass-based solar receivers for solar steam generation.
