When used for water remediation or electrochemical energy storage and conversion, they are nanostructured and exposed to various environments. Therefore, understanding their surface reactivity is of prime importance. Such studies have been hindered by carbon contamination from syntheses. Herein, this synthetic and characterization challenge is addressed through a new approach to 50\u2005nm carbon\u2010free Ti<jats:sub>4<\/jats:sub>O<jats:sub>7<\/jats:sub> and Ti<jats:sub>6<\/jats:sub>O<jats:sub>11<\/jats:sub> nanoparticles. It takes advantage of the different reactivities of rutile and anatase TiO<jats:sub>2<\/jats:sub> nanoparticles towards H<jats:sub>2<\/jats:sub>, to use the former as precursor of Ti<jats:sub><jats:italic>n<\/jats:italic><\/jats:sub>O<jats:sub>2<jats:italic>n<\/jats:italic>\u22121<\/jats:sub> and the latter as a diluting agent. This approach is combined with silica templating to restrain particle growth. The surface reactivity of the Magn\u00e9li nanoparticles under different atmospheres was then evaluated quantitatively by synchrotron\u2010radiation\u2010based X\u2010ray photoelectron spectroscopy, which revealed oxidized surfaces with lower conductivity than the core. This finding sheds a new light on the charge transfer occurring in these
