Synthesis of intermetallic transition metal-main group metal nanoparticles in ionic liquids

金属间化合物，即双金属，纳米粒子（NP）与过渡金属/主族金属组合TM/E（TM = Fe，Ni; E = Al，Ga，In）的基础上有机金属前体化学的合成将研究与特别强调的反应控制由离子液体（IL）作为一种非常规的介质。将完成NP在载体上的沉积。在氢化催化的应用将investigated.The预期的进展超出了国家的最先进的是看到在特定的机会提供的前体分解和集群/纳米粒子的生长动力学的反应控制，而不需要额外的稳定剂，通过低温，快速和节能的氢解或微波加热技术的离子液体。因此，离子液体应该有助于克服现有的化学策略的限制，使用传统的溶剂和技术，自下而上的纳米合金和纳米粒子的合成。IL衍生的纳米合金的化学和物理性质，例如，在催化作用中，预期与在存在额外稳定剂的情况下通过常规湿化学方法获得的类似纳米合金不同。

The synthesis of intermetallic, i.e. bi-metallic, nanoparticles (NPs) with transition metal/main group metal combinations TM/E (TM = Fe, Ni; E = Al, Ga, In) based on organometallic precursor chemistry will be investigated with special emphasis on the reaction control given by ionic liquids (ILs) as a non-conventional medium. The deposition of the NPs onto supports will be done. Applications in hydrogenation catalysis will be investigated.The expected progress beyond the state of the art is seen in the specific opportunities offered by ILs for reaction control of precursor decomposition and cluster/nanoparticle growth kinetics without the need of additional stabilizers by low-temperature, fast and energy-saving hydrogenolysis or microwave heating techniques. Thereby ILs should help to overcome limitations of existing chemical strategies using conventional solvents and techniques for bottom-up nanoalloy and nanoparticle synthesis. The chemical and physical properties of IL derived nanoalloys, e.g., in catalysis, are expected to be different from similar nanoalloys obtained by conventional wet-chemical methods in the presence of additional stabilizers.
