Semi‐Artificial Photosynthetic Machinery for Carbon Dioxide Capture and Conversion
Abstract
ABSTRACT Producing value‐added chemicals directly from CO 2 powered by sunlight offers a sustainable approach to addressing both environmental and economic challenges. However, the inherent chemical stability of CO 2 poses a grand challenge in achieving highly active and selective CO 2 conversion. Herein, we develop a biohybrid semi‐artificial photosynthetic system that integrates carbonic anhydrase (CA) and a CuZn nanozyme photosensitizer with a dendritic polymer (PPA) for the sustainable transformation of CO 2 into dimethyl carbonate (DMC). The PPA‐wrapped CA/CuZn can capture CO 2 to form active intermediates. Through photo‐induced charge transfer under visible light illumination, the CA/CuZn@PPA system achieves 100% selectivity for DMC production at room temperature and low CO 2 pressure.
