化石燃料的消耗预计在未来十年不会显著减少，从而推动大气中的二氧化碳浓度上升。随着金属有机骨架等多孔材料吸附剂的发展，碳捕获领域取得了巨大的进展。人们还建立了新的热和电化学催化过程，将二氧化碳还原为甲酸、乙醇或碳氢化合物等有价值的产品。将二氧化碳捕获和转化结合在一个过程中是优化整个过程的一种聪明方法。络合氢化物如硼氢化物（MBH4, M = Na, Li，…）和丙酸盐（MAlH4）在化学中经常用作还原剂。它们也被称为潜在的固态储氢材料。优越的重量氢化物密度赋予这些材料吸引人的特性，以减少二氧化碳。本文综述了络合氢化物，特别是硼氢化物与CO2的反应性，以及这一领域的最新进展。
Fossil fuels consumption is not expected to decrease significantly in the next decade, driving the atmospheric carbon dioxide concentration upward. Tremendous efforts have been made in the field of carbon capture with the development of porous material adsorbents such as metal–organic frameworks. New thermal and electrochemical catalytic processes have also been established to reduce CO2 into valuable products such as formic acid, ethanol, or hydrocarbons. Combining the CO2 capture and transformation in a single process is a clever way to optimize the overall process. Complex hydrides such as borohydrides (MBH4, M = Na, Li,…) and alanates (MAlH4) are frequently used as reducing agents in chemistry. They are also known as potential solid-state hydrogen storage materials. The superior gravimetric hydride density confers to these materials appealing properties for CO2 reduction. This article summarizes the reactivity of complex hydrides, especially borohydrides, with CO2, as well as the recent development in this field.
