Abstract

Carbon dioxide (COQ), a major greenhouse gas released from anthropogenic activities like industrial emissions and fossil fuel combustion, has elevated atmospheric levels, exacerbating global warming. Its chemical inertness has exhibited conversion challenges, though efficient catalysis aids for the transformation into valuable products. Conventional COQ capture and storage (CCS) suffers from high costs, energy intensity, leakage risks, and inefficiencies, while carbon capture and utilization (CCU) has shown a viable alternative by yielding useful chemicals and fuels with economic benefits. Among thermochemical, electrochemical, photocatalytic, and biological pathways with limitations in efficiency, stability, or scalability this review focuses on thermocatalytic COQ hydrogenation to methane. It highlights Ni-Cu bimetallic catalysts confined in zeolitic frameworks, where Ni-Cu synergy and zeolites' tunable acidity/pore structure has helped in COQ activation, CH4 selectivity, and stability. Key synthesis methods and properties are examined to reveal impacts of bimetallic composition and zeolite topology on performance, concluding with challenges and future directions for scalable COQ methanation
