摘要：

The results of a study of Pd/TiO2 and Pd/ZrO2 catalysts prepared by impregnation using different heat treatment conditions in the oxidation reaction of 5-hydroxymethylfurfural (5-HMF) are presented. The catalysts were characterized using XRD analysis, X-ray fluorescence spectroscopy (XFS), low-temperature nitrogen adsorption, and pulse CO adsorption. Catalytic studies were carried out under mild conditions of 5-HMF oxidation at a temperature of 80 degrees C and an oxygen pressure of 5 atm with the use of NaHCO3 as an alkaline agent. It was found that the conditions of thermal treatment significantly affected the formation of an active component in the Pd/TiO2 and Pd/ZrO2 catalysts and determined the dispersity of the active component, its interaction with the support, and, as a consequence, the catalytic properties of the resulting materials.
