| Abstract: | The Nozaki Ir-based CO2 hydrogenation catalyst was successfully immobilized on post-functionalized silica beads (d=200 μm) through click chemistry. This material hydrogenates CO2 into formic acid with turnover numbers reaching 2.8×104 in a batch reactor within 24 hours, paving the way towards the design of efficient heterogeneous catalysts for this transformation. |
