Environmental pollution and clean water production are challenges to the development of human society. In this paper, devices consisting of a superhydrophobic Ni-CoFeO foam layer (floating layer), a hydrophilic channel and a superhydrophilic Ni-CoFeO foam layer (photothermal conversion layer) were designed. The light energy was converted into heat on the photothermal layer, for which the hydrophilic channel provided a small amount of water. The superhydrophobic layer ensured the floating and selective adsorption of organic solvents on the water surface, whose contact angle reached 157°, and the steam production rate reached 1.68 kg·m·h. Finally, the LSV curve demonstrated that the Ni-CoFeO foam prepared had a minimum starting potential, achieving the multifunctionality of the Ni foam.
环境污染和清洁水生产是人类社会发展面临的挑战。本文设计了一种由超疏水Ni-CoFeO泡沫层（漂浮层）、亲水通道和超亲水Ni-CoFeO泡沫层（光热转换层）组成的装置。光能在光热层上转化为热量，亲水通道为此提供少量的水。超疏水层确保有机溶剂在水面上漂浮和选择性吸附，其接触角达到157°，产汽速率达到1.68 kg·m⁻²·h⁻¹。最后，线性扫描伏安曲线表明制备的Ni-CoFeO泡沫具有最小起始电位，实现了泡沫镍的多功能性。
