We report on the interaction of silicon nanocrystals with water/alcohol solutions which results in their complete oxidation, the hydrolysis of water and hydrogen generation in amounts close to the ideal scenario. Water acts as an oxidizer while alcohol is required for efficient wetting of nanosilicon. This process results in the formation of silicon-based alcogel which can be further transferred to aerogel.
我们报告了硅纳米晶体与水/醇溶液的相互作用，导致它们完全氧化、水解并产生接近理想情况的氢气。水充当氧化剂，而醇则需要有效地润湿纳米硅。这一过程导致了硅基醇凝胶的形成，后者可以进一步转化为气凝胶。
