Concentration-Dependent Solar Thermochemical CO2/H2O Splitting Performance by Vanadia–Ceria Multiphase Metal Oxide Systems

Figure 5

Oxygen exchange performance of vanadia–ceria metal oxide systems: (a) oxygen evolution rates calculated from the amounts of CO and CO2 (referred in text as O1) and (b) oxygen signal from a mass spectrometer (referred in the text as O2) during the reduction and oxidation steps of MPO–CDS, MPO–WS, MPO–WS–CDS, and MPO–CDS–WS redox cycles. The vertical-scale break in (b) denoted by the dash is from 50 to 150 .
