In situ FTIR study of the kinetics of formic acid decomposition on V–Ti oxide catalyst under stationary and non-stationary conditions. Determination of kinetic constants

Decomposition of formic acid over V–Ti oxide catalyst under stationary and non-stationary conditions was studied by in situ IR spectroscopy at temperature range 50–150 °C. The kinetic scheme was shown to include the steps of reverse adsorption of formic acid and formate decomposition to CO. The rate constants and activation energies were estimated according to the proposed kinetic model. The kinetic model satisfactorily describes the experimental data under stationary and non-stationary conditions.
