New spin on molecular oxygen

ScienceDaily | 7/17/2019 | Staff
Along with collaborators from Slovakia and the United Kingdom, graduate student Yuuki Adachi from Osaka University's Department of Applied Physics has recently published this research in ACS Nano.

Oxygen is one of the most abundant elements on Earth. Usually found in its diatomic form, O2, oxygen is highly reactive and doesn't hang around long in a gaseous state. The ground state, or least reactive form of oxygen, is referred to as triplet oxygen because it has three possible arrangements of electron spins. However, singlet oxygen, with its one possible spin arrangement, is more reactive and plays a major role in a diverse range of chemical reactions, ranging from green fuel production to photodynamic cancer treatments.

Interest - Formation - Activation - Oxygen

Unsurprisingly then, there is significant interest in controlling the formation and activation of molecular oxygen.

"We used Kelvin probe force spectroscopy to examine the charge states of oxygen atoms attached to a titanium dioxide rutile surface, and to then manipulate the charge through the transfer of individual electrons to and from pairs of oxygen atoms," explains...
