A method for separating metal ions from a liquid includes a step of providing a solution having metal-containing ions and associated negative counter ions in a liquid. The metal-containing ions are contacted with a dendrimer to form solid particles of metal-containing ion-dendrimer complexes. The solid particles of metal-containing ion-dendrimer complexes are separated from the solution.

Metal oxides having a lower activation temperature and enhanced oxygen mobility are disclosed. The metal oxides comprise oxygen (O), cerium (Ce) and one or both of iron (Fe) and uranium (U). Also disclosed are methods for producing hydrogen or carbon monoxide from water or carbon dioxide using the metal oxides.
