一种碱性形式的“干水”——一种“干碱”——是通过金属碳酸盐或有机胺的水溶液与疏水二氧化硅纳米粒子的高速混合制备的。尽管大部分是水,但干燥的基底看起来和流动起来都像粉末,由于其高表面体积比,可以快速吸附二氧化碳而不需要任何混合。与普通的水溶液不同,干碱可以是无腐蚀性的,因为它们不容易弄湿表面。
An alkaline form of 'dry water' -a 'dry base'-is prepared by the high-speed mixing of aqueous solutions of metal carbonates or organic amines with hydrophobic silica nanoparticles. Despite being mostly water, the dry base looks and flows like a powder, and adsorbs CO2 rapidly without any mixing because of its high surface-to-volume ratio. Unlike normal aqueous base solutions, dry bases can be non-corrosive because they do not readily wet surfaces.
