Templated Synthesis of Carbon-Free Mesoporous Magnéli-Phase Titanium Suboxide
Titanium suboxides, such as the Magnéli-phase Ti x O 2 x –1 , have attracted much attention as candidates of stable electrode materials because of their high conductivity and stability. The synthesis of porous titanium suboxides with high surface area without the formation of residual carbon is impo...
