Photoelectrochemical Performance of Nb-doped TiO2 Nanoparticles Fabricated by Hydrothermal Treatment of Titanate Nanotubes in Niobium Oxalate Aqueous SolutionLizhen Long1,2,Liangpeng Wu1,Xu...="ChDivSummary">Nb-doped TiO2 nanoparticles were prepared by hydrothermal treatment of titanate nanotubes in niobium oxalate aqueous solution.The effect of Nb doping and rutile content......
) was leached with the mixture of HF and H2SO4, HF and HNO3 acids, respectively. Optimal conditions ensuring high recovery of tantalum and niobium (up to 99%) into solution, and radionuclides into insoluble residue were determined. Fluoride-sulfuric acid and fluoride-nitric acid schemes were proposed for PMC leaching by an extractive separation of tantalum form niobium, lead and impurities, and production......
