A series of CexZr1-xO2 supports with different Ce/Zr molar ratios were utilized for the preparation of gold catalyst used in the selective oxidation of 5-hydroxymethyl-2- furfural to 2,5-furandicarboxylic acid. The used method of gold deposition allows the preparation of homogeneous gold particles size and shape distribution, a formulation very useful for studies dedicated to reveal the support participation in the reaction. The supports are characterized by FTIR using CO as probe molecule and the sample catalytic activity is thereafter correlated to the support acid sites distribution. The possible participation of its Lewis/Bronsted acidity in the reaction mechanism is also proposed.
