The use of solar energy to produce steam is an effective method to purify sewage or seawater. Herein, we deposited TiN nanoparticles (NPs) on a piece of carbonized wood as a new type of double layer material for solar water evaporation. TiN NPs possess better stability, lower cost, lower toxicity and wider and stronger optical absorption than the previously reported photo-thermal conversion (PTC) materials, such as plasmonic metals, carbon-based materials and semiconductor nanomaterials. The amounts of TiN NPs and the thicknesses and types of the substrates have important influences on water evaporation rates and solar-vapor conversion efficiency. A solar-vapor conversion efficiency of 92.5%, the highest efficiency in the reported wood-based PTC materials, is obtained under 1-sun simulated solar irradiation. In addition, the TBCF hybrid materials (TiN NPs on biocarbon foam) exhibit good reusability.

利用太阳能产生蒸汽是净化污水或海水的有效方法. 本文中, 我们将氮化钛纳米颗粒沉积在经过碳化处理的木块上, 得到一种新型 的双层太阳能蒸汽发生材料. TiN纳米颗粒具有比以往报道过的光热转换材料(如等离子体金属、碳基材料和半导体纳米材料)更好的稳 定性、更经济的价格、更低的毒性、更宽和更强的光吸收等多重优点. TiN纳米颗粒的沉积量以及基底的厚度和类型对水的蒸发速率和 太阳能-蒸汽转换效率有重要影响. 在模拟太阳光强度为1 kW m−2下, 该材料具有92.5%的太阳能-蒸汽转换效率, 这是已知的木基光热转 换材料中的最高效率. 此外, 该材料具有良好的可重复利用性.
