Design of Novel Photocatalyst for Green CO2 Reduction

Various technologies have been developed to reduce CO₂ emissions and achieve net-zero energy sectors. One common method is carbon capture and storage, which traps CO₂2 using special materials. However, they are facing challenges in handling the captured CO₂ for long-term storage and potential secondary emissions. Converting CO₂ into useful products thus offers a promising solution to both reduce CO₂ emissions and meet energy needs. However, because CO₂ is a stable and inert molecule, converting it into useful products can be challenging. Existing techniques for CO₂ conversion, including electrochemical, thermal, and radiolysis methods, are energy intensive and not eco-friendly.

 

Researchers at Arizona State University have developed a novel photocatalyst designed to efficiently convert CO₂ into valuable fuels. This technology leverages the synergistic interaction between the materials to enable enhanced light absorption and photocarrier generation. It boosts light absorption via the interaction between plasmonic and Mie resonances and improves CO₂ conversion. This photocatalyst provides a sustainable, cost-effective and eco-friendly solution for reducing CO₂ emissions beyond carbon capture, contributing to global efforts to combat climate change and promote a low-carbon economy.

 

This novel photocatalyst has been designed to have superior CO₂ reduction efficiency and has significant potential in the fields of renewable energy, carbon capture, and sustainable chemical production.
