Paragraph starter
The efficiency of light-driven carbon dioxide reduction is significantly influenced by the surface area of the photocatalyst. Research indicates that materials with higher surface area, such as nanostructured catalysts, exhibit enhanced performance in converting CO2. This suggests that for sustainable design solutions involving CO2 capture and conversion, prioritizing materials and manufacturing processes that maximize surface area is a critical consideration for improving system efficacy.
