제목 Effect of oxygen vacancy concentration on the activity of Pd/Ce-ZrO2 catalysts for decarboxylation of oleic acid
초록 The Ce/Zr ratio of Pd/Ce-ZrO2 catalysts was systematically changed to investigate the effect of oxygen vacancy concentration on their decarboxylation activity. Pd/Ce0.5Zr0.5O2 exhibited the highest catalytic activity due to the highest oxygen vacancy concentration, as shown by XPS and Raman spectroscopy results. A catalyst deactivation study also exhibited that the oxygen vacancy concentration influences the catalytic activity. The catalyst deactivation occurs because of Pd sintering, decreases in the BET surface area and Pd dispersion, and the loss of oxygen vacancies.
