Today, heterogeneous catalysis appears to be a powerful tool in the domain of carbon dioxide (CO₂) utilization owing to its outstanding activity and recyclability. In this context, numerous novel heterogeneous catalysts for the transformation of CO₂ and aromatic amines towards nitrogen heterocycles have been fabricated. Herein, a highlighted overview on the eco-friendly construction of CO₂-based heterocyclic frameworks under heterogeneous condition is introduced. In addition, the mechanistic pathways on catalytic fixation of CO₂ are also delineated to clarify the crucial role of active sites on these solid catalysts.
