Claim 0:
1. A method of producing porous multi-metal oxide nanotubes, comprising steps of:
preparing an admixture comprising metal-acetyl acetonate precursors, polyacrylonitrile (PAN) and a solvent component;
producing a nanocomposite from the admixture,
wherein metals of the metal-acetylacetonate precursors comprise a first non-radioactive stable isotope and a second non-radioactive stable isotope,
wherein the first non-radioactive stable isotope comprises one or more selected from the group consisting of titanium (Ti), cerium (Ce), strontium (Sr), lanthanum (La), gadolinium (Gd), erbium (Er), scandium (Sc), palladium (Pd), osmium (Os), dysprosium (Dy), ytterbium (Yb), indium (In), and neodymium (Nd), and
wherein the second non-radioactive stable isotope comprises one or more selected from the group consisting of zirconium (Zr), niobium (Nb), yttrium (Y), tantalum (Ta), vanadium (V), molybdenum (Mo), silicon (Si), ruthenium (Ru), tin (Sn), tungsten (W), uranium (U), seaborgium (Sg), and tellurium (Te).
