Hot article: N-doped titanium dioxide for Li-ion batteries

In their NJC paper, George Hasegawa and co-workers (Kyoto University, Japan) demonstrate facile synthesis of hierarchically porous N-doped TiO2 and applications to the anode of Li-ion batteries.

The precursor titanium-based hybrid gels were prepared by crosslinking titanium alkoxide with ethylenediamine in a non-hydrolytic sol-gel route which leads to TiO2 homogeneously doped with a high amount of nitrogen. The combination of N-doping into TiO2 and hierarchically porous structure effectively improves electrode performance; the resultant N-doped anatase showed good discharge capacities higher than the capacity of conventional anatase electrodes.
