  • Publication number: 20230173435
    Abstract: Embodiments described herein relate generally to durable graphene oxide membranes for fluid filtration. For example, the graphene oxide membranes can be durable under high temperatures non-neutral pH, and/or high pressures. One aspect of the present disclosure relates to a filtration apparatus comprising: a support substrate, and a graphene oxide membrane disposed on the support substrate. The graphene oxide membrane has a first lactose rejection rate of at least 50% with a first 1 wt % lactose solution at room temperature. The graphene oxide membrane has a second lactose rejection rate of at least 50% with a second 1 wt % lactose solution at room temperature after the graphene oxide membrane is contacted with a solution that is at least 80° C. for a period of time.

  • Patent number: 9359204
    Abstract: A plurality of mesoporous metal nitride materials may be formed by a method that includes treating with ammonia (or a related bonded nitrogen and hydrogen containing reducing material) a mixed metal oxide material that comprises at least one first metal that forms an unstable product with ammonia and at least one second metal that forms a stable product with ammonia to form the metal nitride materials that include the second metal but not the first metal. The method contemplates forming metal nitride materials, as well as metal oxynitride materials. A related method that uses a non-bonded nitrogen and hydrogen containing reducing material may yield a mesoporous metal oxide. In particular the at least one metal that forms an unstable product with ammonia comprises zinc metal.
