Carbon dioxide, a major by-product of coal and natural gas fueled power plants, is a primary target for reduction of greenhouse gases. Two current approaches to produce inorganic membranes, gas phase synthesis and colloidal synthesis, are subject to defects in the deposition method and surface and…

Supported Pd-alloy membranes separate hydrogen from gas mixtures and enable hydrogen as an energy carrier. However, the dense Pd-alloy (PdA) structure only allows hydrogen gas to pass in the form of interstitial H atoms, which inhibits transfer of other gases through the membrane. Selective remova…
