Here, we demonstrate the use of Pt0 nanoparticles immobilised on a polymeric monolithic support as a ligand-free heterogeneous catalytic system for the reduction of 13CO2 at room temperature and atmospheric pressure. The described system effectively reduces 13CO2 with dihydrosilanes as the hydrogen source to yield a mixture of silylformates, silylacetals and methoxysilanes, which upon further hydrolysis with D2O, produces their respective C1-type products, that is H13COOD, 13CH2(OD)2 and 13CH3OD. If a monohydrosilane was used as the hydrogen source, a selective reduction of 13CO2 to a product mixture of only silylformates was observed. Addition of diethylamine to this reaction mixture results in the formation of H13COOH and Et 2N13CHO. This robust catalytic system is not only maintenance-free and simple to handle, as compared with organometallic and organocatalyst systems, but also shows 3- to 11-fold better catalytic activity and exhibits higher turnover numbers (TONs) up to 21 900 (activity=6.22 kg CO 2 gPt-1 bar-1).
