大气中二氧化碳含量不断增加所造成的环境和社会后果是社会目前面临的最重大挑战之一。二氧化碳的利用，即二氧化碳要么被直接利用，要么被转化为更有价值的产品，很可能成为减少二氧化碳排放的广泛战略的一个组成部分，这一挑战将需要技术和政策的改变。催化是二氧化碳成功转化为增值产品的关键。在这里，我们为《ACS催化》的读者提供关于二氧化碳转化的化学和生物系统的评论，重点是提供该领域的总体观点，而不是技术细节。我们讨论了与二氧化碳转化为特定产品(如一氧化碳、甲酸、甲醇、甲烷、乙烯、燃料、羧酸和聚合物)相关的挑战以及该领域的一般挑战。我们还比较和对比了二氧化碳转化的不同方法，例如均相催化和多相催化或光合作用和非光合作用生物转化，并强调了一种方法可能比另一种方法具有优势的领域。在结束语中，我们确定了与二氧化碳转化有关的问题，这些问题需要解决，才能使技术既可行又减少二氧化碳排放。
The environmental and societal consequences of the increasing levels of carbon dioxide in our atmosphere are among the most significant challenges society currently faces. Carbon dioxide utilization, in which carbon dioxide is either used directly or converted into more valuable products, is likely to be one component of a broad strategy to reduce carbon dioxide emissions, a challenge that will require both technological and policy changes. Catalysis is crucial to the successful conversion of carbon dioxide into value-added products. Here, we provide a review on chemical and biological systems for carbon dioxide conversion directed toward the readers of ACS Catalysis, which focuses on providing a general perspective on the field, rather than technical details. We discuss both challenges related to the conversion of carbon dioxide into specific products such as carbon monoxide, formic acid, methanol, methane, ethylene, fuels, carboxylic acids, and polymers as well as general challenges for the field. We also compare and contrast different methods for carbon dioxide conversion, for example homogeneous versus heterogeneous catalysis or photosynthetic versus nonphotosynthetic biological conversion, and highlight areas where one approach may have advantages over another. In a concluding section, we identify problems related to carbon dioxide conversion that will need to be addressed for technology to be both viable and reduce carbon dioxide emissions.
