| Resumo: | Integrated carbon dioxide capture and utilization (ICCU) technology is being developed to address the challenge of increasing atmospheric CO2 levels. Dual function materials (DFMs) are designed with catalytic and adsorbent components that enable the capture and utilization of CO2 within a single reactor. In this investigation, we systematically evaluated the performance of NiRu-DFMs incorporating oxides of Ca, Na, or a combination to identify effects on both activity and selectivity. Our findings underscore not only the role of adsorbent selection in dictating the overall performance of DFMs but also the pretreatment conditions (in situ reduction). Notably, the highest methanation activity is observed on an as-synthesized (oxidized) 10% Ca-DFM (223.21 μmol/gDFM) at 380 °C, surpassing all other as-synthesized or reduced DFMs. This study sheds light on the relationships between composition, pretreatment, temperature, and performance in DFMs, offering valuable insights into the advancement of new compositions for DFMs. |
