Direct and continuous conversion of flue gas CO₂ into green fuels using dual function materials in a circulating fluidized bed system

Carbon capture and utilization (CCU) technologies, such as CO₂ methanation, generally require energy-intensive CO₂ capture and separation processes prior to catalytic CO₂ conversion. In contrast, integrated CO₂ capture and reduction (CCR) technologies that use dual function materials (DFM) can...

Integrated CO₂capture and selective conversion to syngas using transition-metal-free Na/Al₂O₃dual-function material

Integrated CO2 capture and conversion (ICCC) using dual-function materials (DFMs) is one of the key technologies for addressing critical global environmental and energy issues. DFMs generally consist of alkali or alkaline earth metals for CO2 capture and transition metal catalysts for CO2 conversion. In this study, we studied the ICCC to CO...

Enhanced Activity of Integrated CO₂Capture and Reduction to CH₄under Pressurized Conditions toward Atmospheric CO₂Utilization

A desirable process for realizing a low-carbon society is the direct conversion of dilute CO2 from flue gases or air into highly concentrated hydrocarbons without a need for separate CO2 capture and purification processes. In this study, we investigated the performance of integrated CO2 capture and reduction to CH4 over Ni-based dual...
