Advancing carbon capture with bio-inspired membrane materials: A review

This paper presents an innovative approach to carbon capture using bio-inspired membrane materials, addressing the urgent need to combat climate change and reduce atmospheric CO₂ levels. Traditional carbon capture technologies face limitations such as high operational costs and limited efficiency. In contrast, bio-inspired membranes, drawing from the efficiency and specificity of natural systems, offer higher CO₂ selectivity, reduced energy requirements, and increased sustainability. The paper explores the design principles and carbon capture mechanisms of bio-inspired membranes, highlighting significant advancements in material synthesis and structure. Key strategies include extreme wettability, facilitated transport mechanisms, and the use of porins and nanochannels. The integration of artificial photosynthesis and enzyme technologies into membrane systems is also examined. Innovations in material synthesis and composite development are showcased, demonstrating enhanced CO₂ separation across various industrial applications. Despite these promising attributes, bio-inspired membranes face significant challenges such as loss of mobile carriers, inadequate compatibility between polymeric matrices and facilitating agents, and difficulties in scaling up due to complex fabrication processes. These challenges underscore the need for continued research to optimize membrane design and functionality, ensuring their viability for large-scale implementation. The paper underscores the transformative potential of bio-inspired membrane materials in advancing carbon capture technologies, aligning with global efforts to mitigate climate change and achieve sustainable development goals.
