Carbon capture technologies play a critical role in mitigating climate change by removing carbon dioxide (CO₂) from industrial emissions and the atmosphere. According to the International Energy Agency, carbon capture systems could eliminate up to 20% of greenhouse gas emissions by 2050.
Despite their environmental benefits, carbon capture systems are often energy intensive. They consume large amounts of energy, which increases operational costs and contributes to emissions. However, advanced materials can improve CO₂ adsorption rates, helping reduce energy demand, operating costs, and the environmental impact of carbon capture systems.
For carbon capture technology firms looking to improve efficiency, independent testing demonstrates a clear material advantage for mesoporous silica solid sorbents. According to tests conducted by the University of Cincinnati, solid sorbents with larger pores, like RESIFA™ SOLESPHERE™ silica, deliver stronger adsorption performance than competing materials. Large pore volumes and pore diameters support higher amine loading, which improves CO₂ capture efficiency while reducing regeneration energy demand and operating costs.
What Are Amine-Treated Mesoporous Silicas?
Mesoporous silicas, such as SOLESPHERE grades, are highly effective solid sorbent materials for CO₂ capture. Amine-treated silica particles provide high CO₂ adsorption capacity, helping improve carbon capture efficiency across industrial and direct air capture applications. These silica grades also demonstrate excellent thermal and mechanical stability.
How Porous SOLESPHERE Silica Improves CO₂ Capture
Pore structure and pore volume significantly affect the performance of solid sorbents used in carbon capture systems. Recent thermogravimetric analysis conducted by Dr. Joo-Youp Lee at the University of Cincinnati shows that SOLESPHERE grades deliver strong adsorption performance for better carbon capture efficiency. The combination of porosity, pore volume and pore diameter supports several advantages in carbon capture applications.
Higher Amine Loading Capacity
SOLESPHERE microspherical silica is engineered for high-performance amine loading in CO₂ capture applications. Its optimized particle size and porosity, along with a large pore volume andstructure, provide an excellent foundation for amine treatments

Increased Adsorption Rate
The porous structure of SOLESPHERE silica supports CO₂ adsorption capacity. Amine-treated SOLESPHERE silica can adsorb more CO₂ than competing silicas, especially at low concentrations (e.g., 400ppm ). Using the same amine, SOLESPHERE silica improved the adsorption performance by 25% compared to the benchmark silica, which was originally designed for this application.

Better System Efficiency
Carbon capture systems require significant energy to remove CO₂ from industrial emissions and ambient air. Porous solid sorbents can improve the efficiency of these systems, such as SOLESPHERE silica. SOLESPHERE grades contribute to higher CO₂ adsorption capacity and require fewer carbon capture cycles, helping reduce energy consumption and operating costs.
