Abstract
The Pd/N-C catalysts based on the carbon support Sibunite modified by the introduction of nitrogen by the treatment in NO under static reactor conditions were developed. It has been established that at a temperature up to 120 oC the conversion of formic acid is higher over the system Pd/N-C in comparison with the unmodified Pd/C catalyst. X-Ray photoelectron spectroscopy was used to identify the states of nitrogen and palladium in the resulting systems. Transmission electron microscopy was used to study the particle formation trends in the Pd/C and Pd/N-C catalysts, as well as their thermal stability.
