Angew Chem Int Ed Engl:新技能解锁——从空气中收集水

2019-06-15 不详 网络

从空气中收集水是一种很有前景的淡水生产策略,特别适用于缺乏直接清洁水的地区。尽管高浓度液体吸附剂具有高吸附能力,但它尚未广泛用于大气水收集,主要受到解吸困难的限制。 在本文中,我们表明,基于耐盐的GO基气凝胶的界面太阳能加热可以使高浓度液体吸附剂(CaCl250wt%溶液)基于大气水发生器。在相对湿度~70%的条件下,可以生产2.89 kg m-2 day-1的淡水,只有太阳能输入和解吸能量高达6

从空气中收集水是一种很有前景的淡水生产策略,特别适用于缺乏直接清洁水的地区。尽管高浓度液体吸附剂具有高吸附能力,但它尚未广泛用于大气水收集,主要受到解吸困难的限制。

在本文中,我们表明,基于耐盐的GO基气凝胶的界面太阳能加热可以使高浓度液体吸附剂(CaCl250wt%溶液)基于大气水发生器。在相对湿度~70%的条件下,可以生产2.89 kg m-2 day-1的淡水,只有太阳能输入和解吸能量高达66.9%。

这种低成本和有效的方法为从空气中提取水,缓解干旱,内陆和其他缺水地区的干渴提供了一条有吸引力的途径。
