Sorbent Mediated Electrocatalytic Reduction of CO2 to Methane

Brief Description

A groundbreaking technology that efficiently transforms dilute CO2 streams into methane using sorbent materials and electrocatalysis.

Full Description

This technology leverages a novel approach by using sorbent materials to capture CO2 from dilute streams and directly convert it into methane, bypassing the need for energy-intensive regeneration processes. Utilizing an N- heterocyclic carbene sorbent and an iron tetraphenyl porphyrin chloride electrocatalyst, it achieves high Faradaic efficiency in methane production while regenerating the sorbent for reuse.

Suggested uses

• Renewable energy and green chemistry sectors for sustainable fuel production. 
• Industrial CO2 emitters looking for cost-effective carbon capture and utilization solutions. 
• Chemical manufacturing industries seeking new pathways to synthesize valuable commodities from CO2.

Advantages

• Efficient conversion of dilute CO2 streams to methane with high Faradaic efficiency. 
• Eliminates the need for energy-intensive CO2 regeneration steps. 
• Enables the direct use of more economical and readily available dilute CO2 streams. 
• Generates methane, a valuable commodity and fuel, directly from CO2. 
• Operates at ambient temperatures and pressures, enhancing energy efficiency and safety.
