Synthesis of Biogenic Silica as Catalyst Support for Catalytic Methane Combustion

Short Introductive summary

This study addresses the pressing need for sustainable energy sources and materials amid global concerns about climate change and the depletion of non-renewable resources. It investigates the potential of utilizing biomass residues from agricultural food production in Africa as a renewable energy source and a means of producing biogenic silica for various applications. The research demonstrates that biomass residues in Africa offer a sustainable source of high-quality amorphous silica with significant potential for applications in catalyst support and advanced materials. The engineered silica exhibits improved textural properties compared to the original material, transforming its pore network structure. The practical application of silica as a catalyst support reveals its exceptional catalytic activity for methane combustion, surpassing a commercial catalyst in conversion temperature and stability. The cornhusk SiO2 support’s superior surface area and reducibility contribute to its enhanced catalytic performance.
