Abstract
Hierarchically porous N-doped TiO2 materials have been synthesized from macroporous inorganic–organic hybrid gels composed of titanium bridged with ethylenediamine. Homogeneously dispersed nitrogen in the precursor gel networks leads to TiO2 doped with a large amount of nitrogen, which delivers high discharge capacity and good cycle performance as a negative electrode for Li-ion batteries.
