CO₂ chemistry has drawn considerable attention as abundant, low cost, and renewable carbon source in the past decades. The natural stability of CO₂ made its utilization a daunting challenge under mild conditions. Recently, there has been significant progress of CO₂ fixation by using cheap and abundant functionalized polyoxometalate (POM) catalysts. In this review, the POM catalytic system for transformation of CO₂ into valuable compounds such as urea, cyclic carbonate, quinazoline-2,4(1H,3H)-diones, α-methylene cyclic carbonate, oxazolidinones etc. were discussed. The future of POM catalysis for sustainable chemistry lies in the synthesis of highly functionalized task-specific POM catalysts, and rational design of novel reactions which would eventually pave the pathway for the establishment of green, effective, inexpensive and sustainable technologies.

在过去的几十年中，CO ₂化学以其丰富，低成本和可再生的碳源而备受关注。CO ₂的自然稳定性使其在温和条件下的利用成为艰巨的挑战。最近，通过使用廉价且丰富的官能化多金属氧酸盐（POM）催化剂，CO ₂固定化取得了重大进展。在这篇综述中，POM催化系统将CO ₂转化为有价值的化合物，例如尿素，环状碳酸酯，喹唑啉-2,4（1 H，3 H）-二酮，α-亚甲基环状碳酸酯，恶唑烷酮等。用于可持续化学的POM催化的未来在于合成高度功能化的特定任务的POM催化剂，以及合理设计新颖的反应，这些最终将为建立绿色，有效，廉价和可持续的技术铺平道路。
