| Abstract Scope |
Nanoporous oxide materials are an essential component of nanoscale scaffolding, many chemical reactions, and drug delivery applications due to their high surface area and low weight. Currently, these nanoporous meshes are made by a variety of chemical dealloying processes where traditionally strong acids and other corrosive liquids are needed to dissolve select elements away from a premade alloy. The purpose of this research is to replicate this process but to avoid the hazardous and wasteful nature of chemical dealloying by oxidatively dealloying off molybdenum in an atmospheric environment; as molybdenum forms a volatile oxide above 500oC which sublimes off, leaving the alloyed elements behind. Current work has shown that this process is a viable method for nanoporous zirconium oxide production with an additional discussion for predicting future successful nanoporous metal oxide systems via these methods. |
