Atmospheric carbon dioxide levels have been rising since the industrial revolution, with the most dramatic increase occurring since the end of World War II. Carbon dioxide is widely regarded as one of the major factors contributing to the greenhouse effect, which is of major concern in today's society because it leads to global warming. Photosynthesis is Nature's tool for combating elevated carbon dioxide levels. In essence, photosynthesis allows a cell to harvest solar energy and convert it into chemical energy through the assimilation of carbon dioxide and water. Therefore photosynthesis is regarded as an ideal way to harness the abundance of solar energy that reaches Earth and convert anthropologically generated carbon dioxide into useful carbohydrates, providing a much more sustainable energy source. This Minireview aims to tackle the idea of immobilizing photosynthetic unicellular organisms within inert silica frameworks, providing protection both to the fragile cells and to the external ecosystem, and to use this resultant living hybrid material in a photobioreactor. The viability and activity of various unicellular organisms are summarized alongside design issues of a photobioreactor based on living hybrid materials.
自工业革命以来，大气中的二氧化碳水平一直在上升，自第二次世界大战结束以来，二氧化碳的增长最为显著。二氧化碳被广泛认为是导致温室效应的主要因素之一，而温室效应是当今社会关注的主要问题，因为它会导致全球变暖。光合作用是自然界对抗二氧化碳升高的工具。从本质上讲，光合作用允许细胞通过捕获太阳能并将其转化为化学能来吸收二氧化碳和水。因此，光合作用被认为是利用到达地球的丰富太阳能的理想方法，并将人为产生的二氧化碳转化为有用的碳水化合物，提供更可持续的能源。这篇综述旨在探讨将光合单细胞生物固定在惰性二氧化硅框架内的想法，为脆弱的细胞和外部生态系统提供保护，并在光生物反应器中使用这种活的杂交材料。总结了各种单细胞生物的生存能力和活性，以及基于活的杂交材料的光生物反应器的设计问题。
