Biocatalytic tough protein hydrogel for carbon sequestration |
| 초록 |
Development of carbonic anhydrase (CA)-based materials for environmentally-friendly sequestration carbon dioxide (CO2) under mild conditions would be highly valuable for controlling emissions to the environment and for producing value-added chemicals. Here, a highly tough and stable CA-encapsulated silk protein hydrogel was developed for CO2 sequestration through a bioinspired dual-crosslinking strategy that employed photo-induced dityrosine chemical crosslinking followed by dehydration-mediated physical crosslinking. The dual-crosslinked CA-encapsulated silk hydrogel facilitated the sequestration of CO2 into calcium carbonate with high CO2 hydration activity. The dual-crosslinked CA-encapsulated silk hydrogel exhibited a significant mechanical properties and structural stability. Thus, the unique combination of bioinspired dual-crosslinking with silk fibroin protein and CA enzyme demonstrates the successful application of protein hydrogel for CO2 sequestration. |
