AI Technical Summary
Technical Problem
Existing technologies make it difficult to prepare supported catalysts with high metal utilization and uniform coordination environment, resulting in insufficient catalyst activity and selectivity.
Method used
A double single-atom catalyst rich in defect sites, consisting of CeO2 nanorods loaded with noble and non-noble metals, was prepared by mixing Ce salt and non-noble metal salt solutions with a strong base, followed by hydrothermal treatment and calcination.
Benefits of technology
Under mild conditions, the catalyst exhibits high activity, selectivity, and stability, making it suitable for the selective hydrogenation of unsaturated aldehydes/nitro compounds and alkynes.
