title: Direct thermolysis of CO2into CO and O2.
abstract: Most of the solar-driven thermochemical CO2dissociation reactions have been focused on two-step processes. In this study, a one step CO2thermolysis process was considered. It was found that direct thermolysis of CO2obviously occurred at temperatures as low as 1200 °C within a corundum tube. The reaction rate could be enhanced by several times in the presence of metal oxides, which may be attributed to the catalysis of oxygen vacancies in the metal oxides.
