Glycerol Conversion to Lactate over Pt/Ce-ZrO2 Catalysts: Influence of Support Doping on Selectivity and Stability
Short Introductive summary
Glycerol valorization provides a sustainable route to high-value chemicals from biomass-derived waste. We report Pt catalysts supported on ZrO? and Ce-doped ZrO? for glycerol dehydrogenation to lactate (LA). Catalytic performance was strongly support-dependent. Pt/5CeZrO? achieved the highest LA yield of 89.5% and a turnover frequency of 7577 h?¹ at 1 h. This TOF represents the highest value reported for heterogeneous glycerol dehydrogenation. Ce doping generated abundant oxygen vacancies and Lewis acid sites. These features induced lattice strain and stabilized ultrafine ~1 nm Pt nanoclusters. Enhanced metal–support interfaces promoted efficient conversion and selectivity. The system operated under harsh conditions (200 °C, 9 M KOH) with outstanding stability. Industrial metrics included 75% glycerol feed, 12.6 kgLA L?¹ day?¹ space-time yield, and 5.8 mol H? L?¹ day?¹ co-production. Correlation of LA selectivity with lattice strain revealed key structure–activity relationships. Recycling tests confirmed catalyst robustness and scalability for biomass valorization.
