Hierarchically porous monoliths of oxygen-deficient anatase TiO2−x with electronic conductivity
Abstract
We report an electrically conducting oxygen-deficient anatase TiO2−x monolith with macro/meso/micro trimodal pores, prepared by reducing insulating porous TiO2 monoliths at low temperature. Without adding any conductive materials, the TiO2−x monolith itself was electrically conducting enough for lithium insertion, potentially opening a new avenue for carbon-free
