Mesoporous wall‐structured TiO 2 on reduced graphene oxide (RGO) nanosheets were successfully fabricated through a simple hydrothermal process without any surfactants and annealed at 400 °C for 2 h under argon. The obtained mesoporous structured TiO 2 –RGO composites had a high surface area (99 0307 m 2 g −1 ) and exhibited excellent electrochemical cycling (a reversible capacity of 260 mAh g −1 at 1.2 C and 180 mAh g −1 at 5 C after 400 cycles), demonstrating it to be a promising method for the development of high‐performance Li‐ion batteries.
