The method of choice for high-precision, minimal-waste chemistry is homogeneous catalysis, and the key to new or improved catalysis is design of new ligands, molecules that can "fine-tune" the behaviour of metals in catalysis. Our research program is aimed at understanding and quantifying ligand properties, connecting these quantities with experimental performance, and through this get the most out of catalytically active metals. One specific purpose is replacing expensive platinum metal catalysts with cheaper elements like iron, cobalt and nickel. Another one is developing catalysts that can break carbon-oxygen bonds (abundant in biomass, the feedstock of the future) without being deactivated by them.

高精度、最少废物化学的选择方法是均相催化，而新的或改进的催化的关键是设计新的配体，即可以“微调”金属在催化中的行为的分子。我们的研究计划旨在了解和量化配体特性，将这些数量与实验性能联系起来，并通过此充分利用催化活性金属。一个具体目的是用铁、钴和镍等更便宜的元素代替昂贵的铂金属催化剂。另一项是开发可以打破碳氧键（生物质中丰富的，未来的原料）而不被其失活的催化剂。
