Metals Oxides as Model Supports for Single Atom Catalysis
Single-atom catalysis (SAC) offers an opportunity to minimize the amount of precious catalyst material required for traditional heterogeneous catalysis and to “heterogenize” reactions presently requiring homogeneous catalysis; this would eliminate the problem of separating catalyst and product, while retaining the excellent selectivity and activity of homogeneous catalysts.
Unravelling how metal atoms bind to metal oxide supports is crucial for a better understanding of the SAC ́s catalytic properties. Using STM, nc-AFM and XPS, we compare several transition metals on different metal oxide support surfaces such as Fe2O3(1-102), rutile TiO2(110) and anatase TiO2(101) and the influence of water on the dispersion of these systems.
This study points out the importance of metal-support interaction and the surprisingly different behaviour of the transition metals on different metal oxide supports.
