太阳能界面蒸发器是利用太阳能这一可持续能源来缓解水资源短缺问题的最有前景的技术之一。为了解决以往太阳能蒸发器工艺复杂、材料成本高及能耗大等问题,以具有分级多孔结构、优异的光吸收性以及超亲水性的碳化玉米芯(C)为原料,在其表面包覆能进一步提高光吸收性能的四羧基苯基卟啉(TCPP),得到了具有较强光热转换效应的C/TCPP整体材料,其在200～2500nm范围具有较强的光吸收性。以C/TCPP作为太阳能界面蒸发器,在1个太阳(1kW/m2)的光照强度下,蒸发速率为5.83kg/(m2·h),实现了快速的海水蒸发。
Solar interfacial evaporation is one of the most promising technologies to alleviate water shortage by using sustainable solar energy.In order to solve the problems of complicated technology,high material cost and high energy consumption of previous solar evaporators,in this study,carbonized corncob with hierarchical porous structure,excellent light absorption and super-hydrophilic performance was used as raw material,and the surface of the carbonized corncob was coated with tetracarboxyphenylporphyin (TCPP),which could further improve the light absorption performance,resulting in the formation of a C/TCPP monolithic material with strong photothermal conversion effect.The C/TCPP material exhibited strong light absorption in the range of 200nm to 2500nm.Using C/TCPP as a solar interfacial evaporator,the evaporation rate was 5.83kg/(m2·h) under the illumination intensity of one sun(1kW/m2),which achieved rapid seawater evaporation.
