The hydrogenation of CO 2 to formic acid can be carried out by numerous homogenous catalysts, while efficient heterogeneous catalysts are rare. In this work, we successfully synthesize an immobilized lutidine‐derived pincer‐type N‐heterocyclic carbene ruthenium complex based on a mesoporous organo‐silica hybrid material using sol‐gel direct synthesis in the presence of structure directing agents and click chemistry as the two key pillars of this strategy. This material efficiently catalyzes the hydrogenation of CO 2 into formate with turnover numbers reaching 18′000 within 24 hours, surpassing the performance of the corresponding homogeneous complexes.
