NiOCaO materials as promising catalysts for hydrogen production through carbon dioxide capture and subsequent dry methane reforming

143CaO-NiO was evaluated as CO2 or CO-O2 chemisorbent and catalytic material for hydrogen production. Results showed that syngas was produced at two different temperatures by CH4 reforming (∼600 °C), using the CO2 previously chemisorbed on CaO, or by CH4 partial oxidation at higher temperatures (T ≥ 800 °C).
