研究领域

1.非贵金属的羰基簇合物的合成与应用：过渡金属簇合物具有特殊的几何结构和氧化形态，在理论研究和催化应用中占据重要地位。我们发现某些混合金属原子簇合物可在室温下迅速加合多个氢原子，并在温和条件下可逆地释放氢气，从而成为一种值得研究的储氢材料。这些簇合物中多含有一种或多种稀有金属如铂、铑、锇等。我们研究的中心将围绕新型非稀有金属如铁、钴、镍的混合金属簇合物，采用新配体以增加分子不饱和度，提高载氢量。在应用方面，着重研究小分子在簇合物金属上的吸附活化机理及其在储能材料方面的应用，以及在催化反面的可能应用。氢气在金属上的活化是加氢脱氢反应的重要步骤，其机理研究对储氢材料的开发和工业催化剂的设计有指导性意义。 2. 含硫的多金属羰基簇合物的成与表征：含硫的金属簇合物除了在仿生学上有重要应用，金属酶的活性中心多以原子簇的形式存在。除此以外，含硫的金属羰基配合物还可用于催化和纳米材料的制备，例如Fe2(CO)6(m-S2) 是制备铁硫薄膜的前导体。通过合成具有新型结构的硫金属羰基配合物以制备新型催化剂。
