Exploring the roles of oxygen species in H2 oxidation at β-MnO2 surfaces using operando DRIFTS-MS

Abstract

Understanding the roles of oxygen species at reducible metal oxide surfaces is key to improving catalyst performance. Here, a combination of operando diffuse reflectance infrared Fourier transform spectroscopy and mass spectrometry are employed to explore the behaviours of oxygen species during H2 oxidation at β-MnO2 surfaces.
