论文摘要
太阳能驱动的界面蒸汽产生用于淡化的蒸汽引起了广泛的关注。但是，对于达到更高的蒸发率和高水质以及具有成本效益且易于制造的设备，可以提供可行的太阳能驱动蒸汽系统，仍然存在重大挑战。在这项研究中，将新型的超黑色油漆黑色3.0（作为完美的太阳能吸收器）引入热粉粉泡沫网络中，使我们能够构建超黑（在太阳能区域中吸收99％）和自动浮动蒸发装置。有效的太阳吸收能力和盐排斥能力的高性能有助于在一个太阳下（1 kW M-2）在2.48 kg M-2 H-1处的淡水高到更早的蒸发率。该界面太阳能蒸发器的每日可饮水产量也达到2.8 kg M-2，即使在多云的冬季天气中，并且在水中保持酸度和碱度范围广泛（pH 1〜14）。这些功能将能够构建一个精心制作，健壮，高效且具有成本效益的太阳能生产系统。
Solar-driven interfacial steam generation for desalination has attracted broad attention. However, a significant challenge still remains for achieving a higher evaporation rate and high water quality, together with a cost-effective and easy-to-manufacture device to provide a feasible solar-driven steam generation system. In this study, a novel ultra-black paint, Black 3.0, serving as a perfect solar absorber is introduced into the hot-pressed melamine foam networks, allowing us to construct an ultra-black (99% absorptance in the solar region) and self-floating evaporation device. The high performing features of effective solar absorptance and salt-rejection capability contribute to a high-to-date evaporation rate of freshwater at 2.48 kg m-2 h-1 under one sun (1 kW m-2). This interfacial solar evaporator has a daily drinkable water yield of 2.8 kg m-2 even in cloudy winter weather and maintains stability in water with a wide range of acidity and alkalinity (pH 1~14). These features will enable the construction of a facilely fabricated, robust, highly-efficient, and cost-effective solar steam generation system for freshwater production.
