摘要
The Haber-Bosch process has been the workhorse of ammonia synthesis for more than a century, but its environmental cost has instigated the search for greener methods of nitrogen activation.Photocatalysis using doped titanium dioxide (TiO2) stands out as a promising method.In this work, we explore the electronic properties of pristine and Ru-loaded TiO2 clusters and the activation of nitrogen, hydrogen and ammonia on these clusters.We study the effect of the cluster size and the role of Ru on the electronic properties of the clusters and their activation capabilities.We show that loading with Ru enhanced the nitrogen fixation ability, yet it does not influence the adsorption of hydrogen and ammonia, avoiding catalyst poisoning.
