Lamellar-structured fibrous silica as a new engineered catalyst for enhancing CO2 methanation
Fuel(2023)
摘要
•The support’s structure affecting pore dimension and deposition of Ni particles.•The lamellar structure of CHE-SM enhances the metal-support interaction.•Ni/CHE-SM obtained high CO2 conversion (88.6%) compared to Ni/CHE-S41 (82.9%).•Ni/CHE-SM depicts the highest coke formation resistance during 50 h stability test.•The high basicity and strong MSI were beneficial in suppressing carbon deposition.
