摘　　要：随着全球经济的快速发展,能源短缺和淡水供应不足成为限制沿海城市发展的重大挑战。通过耦合界面式太阳能海水淡化和CO_(2)还原技术,利用太阳光驱动共性元件材料,以海水为驱动介质,获得清洁的水和能源。采用真空抽滤的方法将WS_(2)@C-PDA/Bi结合在商用的PVDF膜上。在1000 W/m^(2)的光强下,WS_(2)@C-PDA/Bi@PVDF的海水蒸发速率达1.2 kg/(m^(2)·h),CO_(2)转化为CO的产率为9.18 mmol/g。因此,开发的太阳光驱动的共性元件材料为清洁水的生产和CO_(2)的还原提供了一种新的途径。With the rapid development of the global economy,energy shortage and insufficient fresh water supply have become major challenges limiting the development of coastal cities.Through the coupling interface solar desalination and CO_(2)reduction technology,using sunlight to drive the common component materials,seawater as the driving medium,to obtain clean water and energy.WS_(2)@C-PDA/Bi was combined with commercial PVDF membrane by vacuum filtration method.Under the light intensity of 1000 W/m^(2),the evaporation rate of WS_(2)@C-PDA/Bi@PVDF can reach 1.2 kg/(m^(2)·h),and the conversion rate of CO_(2)to CO is 9.18 mmol/g.Therefore,the developed sun-driven generic component materials provide a new way for the production of fresh water and the reduction of CO_(2).
