Sustainable formation of tricarballylic acid from citric acid over highly stable Pd/Nb2O5·nH2O catalysts

[Display omitted] •Nb2O5·nH2O proved to be a stable and efficient catalyst for the dehydration of citric acid at mild reaction temperatures.•Investigation of the interaction of citric acid with the Nb2O5·nH2O surface by 13C MAS NMR.•Synthesis of bifunctional Pd/Nb2O5·nH2O via a low-temperature reduc...
