Carbon-coated rutile titanium dioxide (CRT) was fabricated through an in-situ pyrolysis of titanium-based metal organic framework (Ti₈O₈(OH)₄[O₂CC₆H₄CO₂]₆) crystals. Benefiting from the Tisingle bondOsingle bondC skeleton structure of titanium-based metal organic framework, the CRT possesses abundant channels and micro/mesopores with the diameters ranging from 1.06 to 4.14 nm, shows larger specific surface area (245 m² g⁻¹) and better electronic conductivity compared with pure titanium dioxide (12.8 m² g⁻¹). When applied as anode material for sodium-ion batteries, the CRT electrode exhibits a high cycling performance with a reversible capacity of ∼175 mAh g⁻¹ at 0.5 C-rate after 200 cycles, and obtains an excellent rate capability of ∼70 mAh g⁻¹ after 2000 cycles even at a specific current of 3360 mA g⁻¹(20 C-rate). The outstanding rate capability can be attributed to the carbon-coated structure …
