| Research Abstract |
Pd. silica mixed-matrix membranes with superior H2 permeability and hydrothermal stability at high temperatures were successfully fabricated using a sol. gel method. The Pd. silica layer was quite thin(100. 200 nm) and small Pd particles(several nm) dispersed well in an amorphous silica matrix. The improved hydrogen permeability can be ascribed to the formation of continuous Pd layer in amorphous silica matrix.
