Fig. 3. (a) Photocatalytic rate constants for degradation of methylene blue (MB) and acetone with (a) Ti-G, (b) TiO2/CInter, (c) TiO2–VTi/C, (d) n-TiO2/C (e) c-TiO2/C and (f) TiO2/CSurf, and (b) transient photocurrent response of Ti-G, TiO2/CInter, TiO2–VTi/C, n-TiO2/C and TiO2/CSurf. (c) Lithium-ion and (d) sodium-ion long cycle performance at a current density of 10 C. (e) The optimized model of TiO2 with interlayered carbon and titanium vacancies, (f) the section model of TiO2/CInter of the (010) facet and (g) the corresponding charge density difference.
