A novel nickel catalyst supported on fly ash-derived zeolite ZK-14 for CO2 Methanation via in situ reduction

Key Points

• The central aim is to develop a nickel catalyst supported by fly ash-derived zeolite for efficient CO2 methanation.
• Synthesis of a nickel catalyst using fly ash-derived zeolite ZK-14
• In situ reduction of the catalyst
• Evaluation of catalytic performance in CO2 methanation reactions
• The nickel catalyst demonstrated high activity for CO2 conversion to methane
• Effective utilization of fly ash minimizes environmental pollution
• The in situ reduction method enhanced catalyst stability and performance
