Nanocomposites with rich oxygen vacancies promote sensitive
electroanalysis of Hg(II)

Recently, Yang Meng and his colleagues from the
Institute of Solid State Physics, Hefei Institutes of Physical
Science reported a sensitive electrochemical sensing performance of
Ru-loaded single-crystalline (100) CeO2 nanocomposites toward heavy
metal ions (e.g., Hg(II)).
