Hydrogen oxidation over alumina-supported palladium – nickel catalysts

2015-02-12

Abstract

In nuclear power plants, the concentration of hydrogen generated during the reaction of water with the zircaloy is diminished using the passive autocatalytic recombiners. Pd – Ni/​Al2O3 catalysts were tested in the recombination reaction and compared with the results for Pd/​Al2O3 and Pt/​Al2O3 catalysts. The catalytic reaction was performed in the flowing system under atmospheric pressure with a mixture of 0.5 % H2-air in the stream in dry and wet conditions. The bimetallic, nickel-containing low-priced catalysts revealed a little lower activity than the high-priced Pd/ Al2O3, but their activity per active metal is promising. The lower atomic percentage of palladium in the active Pd – Ni phase resulted in higher turnover frequencies. Small amounts of water in the reaction mixture greatly decreased the catalytic performance but simple drying of the reaction mixture eliminated this effect.
