In the context of CO2 utilization, a number of CO2 conversion methods have been identified in laboratory-scale research; however, only a very few transformations have been successfully scaled up and implemented industrially. The main bottleneck in realizing industrial application of these CO2 conversions is the lack of industrially viable catalytic systems and the need for practically implementable process developments. In this study, a simple, highly efficient and recyclable ruthenium-grafted bisphosphine-based porous organic polymer (Ru@PP-POP) catalyst has been developed for the hydrogenation of CO2 to N,N-dimethylformamide, which affords a highest ever turnover number of 160 000 and an initial turnover frequency of 29 000 h-1 in a batch process. The catalyst is successfully applied in a trickle-bed reactor and utilized in an industrially feasible continuous-flow process with an excellent durability and productivity of 915 mmol h-1  gRu -1 .

一种高效实用的体系，用于使用异质Ru催化剂通过CO2加氢合成N，N-二甲基甲酰胺：从分批流向连续流。

在利用二氧化碳的情况下，实验室规模的研究中已经确定了许多二氧化碳转化方法。但是，只有极少数的改造成功地扩大了规模，并在工业上得以实施。实现这些CO2转化的工业应用的主要瓶颈是缺乏工业上可行的催化系统以及对实际可行的工艺开发的需求。在这项研究中，开发了一种简单，高效且可回收的钌接枝双膦基多孔有机聚合物（Ru @ PP-POP）催化剂，用于将CO2加氢成N，N-二甲基甲酰胺，提供了最高的周转率批处理过程中有160 000个，初始周转频率为29 000 h-1。
