| Outline of Final Research Achievements |
Vanadium is known to have a dissociation ability of nitrogen molecule into nitrogen atoms. Also, active atomic hydrogen is supplied continuously through hydrogen permeable metal membranes.In this study, the possibility of the idea of new ammonia synthesis process by utilizing V-based hydrogen permeable alloy membrane has been investigated in a fundamental manner.
It is found that the deposition of Pd-Ag alloy on the outlet side surface is needed for V-based alloy membrane for hydrogen permeation. While keeping the hydrogen permeation condition, nitrogen gas is flowed to the outlet side surface of the membrane samples, and the reaction gas is examined. As a results, ammonia is formed for the membrane sample coated in a grid pattern with Pd-Ag alloy on the outlet side surface. In addition, the alloying effects on the affinity between vanadium and nitrogen have been investigated by first principle calculation of electronic structures.
