A route to support Pt sub-nanoparticles on TiO2 and catalytic hydrogenation of quinoline to 1,2,3,4-tetrahydroquinoline at room temperature†
Abstract
We report a method to support Pt sub-nanoparticles on TiO2. The feature of this route was that N,N′-(ethane-1,2-diyl)diformamide (ED) acted as both the reducing agent and stabilizing agent. The yield of 1,2,3,4-tetrahydroquinoline could be higher than 99% at room temperature. In addition, the catalyst can be recycled at least 4 times.
