Preparation and characterization of hydrophobic Pt-Fe catalysts with enhanced catalytic activities for interface hydrogen isotope separation.

Liquid phase catalytic exchange reactions are mainly used for separation of hydrogen isotopes from liquid water. Based on the carbon-supported Pt and Pt-Fe catalysts, different hydrophobic Pt and Pt-Fe catalysts were fabricated for use in such reactions. The characterization results indicated the Pt-Fe alloy was formed in the Pt(3)Fe/C catalyst prepared using a citric-acid-assisted NaBH(4) reduction method (CA-NaBH(4)).
