摘要：

This work demonstrates that immobilising molecular catalysts on metal substrates can attenuate their reactivity. In particular, the reactivity towards molecular oxygen of both ruthenium tetraphenyl porphyrin (Ru-TPP) and its Ti analogue (Ti-TPP) on Ag(111) was studied as benchmark for the interaction strength of such metal-organic complexes with possible reactants. Here, Ru-TPP proves to be completely unreactive and Ti-TPP strongly reactive towards molecular oxygen; along with comparison to work in the literature, this suggests that studies into immobilised catalysts might find fruition in considering species traditionally seen as too strongly interacting.
