本世纪的核心挑战之一是充足和可持续的能源供应。在这方面，氢技术的进步，例如从合适的起始材料产生氢，其储存和转化为电能，特别令人感兴趣。除了甲烷和甲醇，可再生资源，如（生物）乙醇和甘油，被认为是有前途的氢生产来源。[1]然而，它们的使用仍然困难，因为所应用的重整工艺在高温（> 200 ° C）下运行。因此，需要用于以更高的反应速率和在更温和的条件下产生氢气的改进技术。目前，氢只能在环境温度下通过金属或金属化合物（例如NaBH 4）与水的反应来生产。然而，这些化合物具有明显的缺点，例如毒性、价格和安全性。据我们所知，目前还没有已知的反应体系能够在室温下以受控的方式从有机产物产生氢。[2]在这里，我们证明了在室温下从甲酸和胺的混合物按需产生氢气的可能性。值得注意的是，甲酸作为氢源是无毒的，并且可以容易地处理和储存。[3]第一章
One of the central challenges of this century is the sufficient and sustainable supply of energy. In this respect, advancements in hydrogen technology, such as the generation of hydrogen from suitable starting materials, its storage and conversion into electrical energy, are of particular interest. Besides methane and methanol, renewable resources, such as (bio) ethanol and glycerol, are considered as promising sources for hydrogen production.[1] Nevertheless, their use remains difficult, as the applied reforming processes run at high temperature (> 2008C). Thus, improved technologies for generating hydrogen at higher reaction rates and under milder conditions are required. At present, hydrogen can be only produced at ambient temperatures by the reaction of metals or metal compounds, for example, NaBH4, with water. However, these compounds have obvious disadvantages, such as toxicity, price, and safety.To the best of our knowledge there is no reaction system known at present which is able to generate hydrogen from organic products in a controlled manner at room temperature.[2] Herein we demonstrate the possibility of generating hydrogen on demand from mixtures of formic acid and amines at room temperature. Notably, formic acid as a hydrogen source is non-toxic and can be handled and stored easily.[3]
