Abstract: CO2 is emerging as an attractive C1 feedstock for producing various chemicals owing to the fact that it is safe, abundant, nontoxic, economical and renewable. Such CO2-based products are not only profitable, but are also alternatives to those derived from petroleum resources, and could therefore lessen petroleum dependence in society. One important chemical, out of diverse chemical products derived based on CO2 as a C1 feedstock, is formic acid, which is a valuable basic chemical in various industries and recently it is being considered as an important energy storage material. Thus, the catalytic hydrogenation of CO2 to formic acid/formate has drawn much attention in the scientific and technological community. Even though numerous studies using homogeneous catalysts are available in the literature, the industrial realization of these catalysts poses difficulties owing to the occurrence of a reverse decomposition of generated product back to CO2 and H2 during the separation step(s). Therefore, the search for the highly active and industrially viable heterogeneous catalyst is highly desirable. In this study, an effective Ir(III) catalyst, heterogenized on a highly porous covalent triazine framework, was synthesized and characterized to have a coordination environment similar to that of its homogeneous counterpart. The catalyst efficiently converts CO2 into formate through hydrogenation with a TON of 15,000 and an initial TOF of up to 5,300 h-1; the synthesized catalyst is stable in air and could be recycled by simple filtration without significant loss of catalytic activity.
