摘要:
A study was conducted to demonstrate spectroscopic and theoretical investigations of transition metal oxides and dioxygen complexes. The study focused on investigating binary transition metal-oxygen molecular species with several metal and oxygen atoms that existed in several structural forms and involved different chemical bonding. It was observed that molecular oxygen had the potential to bond side-on or end-on to a metal center forming dioxygen complexes. These dioxygen complexes were intermediate states for the complete cleavage of the O-O bond to form metal oxides. These species were considered as the simplest model for oxygen binding to metal centers. These models were investigated under well-defined conditions at the molecular level that were free of effects from ligands, solvents, surface active sites, and the crystal lattice.
