The activity of 5%Pd/TiO2 and for the first time 5%Pd/TiO2-5%Na catalysts was evaluated in the liquid phase catalytic hydrodechlorination of chloroform at room temperature and 50°C, using isopropanol as solvent and hydrogen donor. 5%Pd/TiO2-5%Na catalyst showed the best catalytic performance at room temperature and 50°C, with the highest conversion at 50°C (32.5%) after 5 hours of reaction. The incorporation of sodium ions into the support favored both the dehydrogenation of isopropanol and the capture of chloride ions produced during the reaction, both positive for the hydrodechlorination of chloroform. The catalysts were characterized by AAS, mass titration, XRD, BET, hydrogen chemisorption, TPR and TGA. Na and Pd were loaded on the support practically without loss. and the anatase phase of titanium dioxide did not change with the addition of NaOH increased the catalyst's isoelectric point, indicating an increase in catalyst basicity. This can explain the improved activity of Na-containing catalysts. [ABSTRACT FROM AUTHOR]
