Abstract
AbstractMesoporous TiO2/C nanohybrids with large specific surface area and well‐defined pore size distribution are prepared by KOH activation treatment using dental resin monomers as solvent and carbon source. Super‐small sized TiO2 nanoparticles are uniformly distributed in porous carbon to realize a significant improvement of the electrochemical properties. The morphology, BET specific surface area and pore size distribution are characterized by SEM, TEM and N2 adsorption/desorption isotherm, respectively. The prepared mesoporous TiO2/C delivers a reversible capacity as high as 387 mAh/g after 100 discharge/charge cycles at 0.2 C current density (1 C=335 mA/g) in conjunction with a good rate capability (184, 70, and 92 mAh/g at 1, 2, and 5 C current densities, respectively).
