摘要：

Alkaline salt of platinum-incorporated heteropolyoxoniobate [Pt(Nb6O19)(2)](12-) (Pt(Nb6)2) was fabricated and applied for N-formylation of various amines including piperidine under CO2 and H-2 atmosphere. Pt(Nb6)2 achieved the selective formation of 1-formylpiperidine, whereas the absence of Pt species, H-2, and CO2 resulted in a trace amount of the product. The structural characterization revealed that the sandwich-type structure of Pt(Nb6)2 was transformed into Pt nanoparticles incorporated with polyoxoniobates ([Nb6O19](8-)) on the NbOx bulk matrix (NbPOM-PtNPs/NbOx) under reaction conditions. The N-formylation of amines in the presence of CO2 and H-2 proceeded by the bifunctional NbPOM-PtNPs/NbOx where the basic sites of [Nb6O19](8-) and the redox property of Pt promoted the generation of formamides.
