- •
PdAgCu alloy membrane was prepared by sequential depositions of Pd, Ag, and Cu onto the substrate.
- •
The membrane reactor used consists of 5% Ni/Ce0.6Zr0.4O2 catalyst and Pd76Ag19Cu5 alloy membrane.
- •
The reactor showed improvement in the hydrogen production from dry reforming reaction.
- •
The CH4 and CO2 conversions were significantly increased by 3.5 and 1.5 folds, respectively.
- •
The hydrogen selectivity was increased from 47 to 53%.
