CO_2 is a cheap, nontoxic and abundant Cl feedstock, and its chemical utilization is a challenge and important topic. Thus, any efficient reactions using CO_2 as a reagent have positive ramifications on efforts towards carbon management. However, CO_2 is a thermodynamically stable compound, and then its reduction requires high energy substances or electroreductive processes. The potential of homogeneous catalysis for CO_2 fixation has been discussed in recent reviews. Heterogeneous catalysis can offer several technical advantages such as stability, separation, handling and reuse of the catalyst and reactor design. Despite CO_2 activation by heterogeneous catalytic routes were still limited, efforts have been made towards the synthesis of cyclic carbonates, and synthetic gas (CO, H_2) as well as methanol synthesis from CO_2 hydrogenation. This brief review is therefore intended to provide an overview of the research progress on those topics.
