“…More importantly, open space in between nanosheets is conducive to accommodate volume changes, buffering mechanical strain. On the other hand, in particular, TiO2 nanosheet arrays have been 4 synthesized to function as stable scaffolds to be loaded with other materials of high capacity to compensate its intrinsic shortcomings [6][7][8]. It should be noted that utilizing array scaffolds with large exposed surface area can suppress the aggregation of active materials after cycling, ensuring a high capacity retention.…”

Graphite anodes in commercialized lithium ion batteries are meeting the bottleneck for future high-performance electronic devices. Strategies has been applied to improve the cycle and rate capacity of the anode active materials. Herein, a two-step hydrothermal approach is presented to synthesize TiO2@MoS2/C as enhanced anodic electrode. The TiO2@MoS2/C electrode delivers a satisfying cycle performance of 643.4 mAh/g on average at a current of 100 mA/g upon 100 cycles. The comparison study shows that TiO2@MoS2/C are superior to its individual part when assembled into batteries. The result also demonstrates that the support from TiO2 nanosheet arrays is essential to achieve both improved cycle and rate performance. Without TiO2 scaffold as an intermediate, MoS2/C is not able to firmly attach to Ti substrate and tends to be exfoliated upon cycling. Besides, the presence of carbon remarkably improves the poor conductivity of TiO2 and MoS2, which is beneficial to elevate rate capacity at high currents.Keywords：TiO2@MoS2/C; carbon infused MoS2; TiO2 nanosheet arrays; intensified anodes

“…49 The charge transfer resistance (R ct ) mostly contributed to the overall resistance for the electrode. 50,51 The value of R ct for the cycled TS and GTS electrodes was calculated to be 103.2 and 47.9 U, respectively. The lower value of the resistance for the GTS electrode is attributed mainly to the modication of conductive graphene on the TS surfaces.…”

Constant technological progress, as well as the pursuit of "friendly" technologies, leads to intensive work on the development of a new generation of advanced products with strictly defined, unique physicochemical properties dedicated to specific applications. This group of materials includes hybrids based on titanium dioxide and its derivatives, characterised with specific, well-defined physicochemical and structural properties, chiefly determined during their synthesis. Different properties of titania nanoparticles depend on their morphology, crystallite size, and crystalline structure. Nanocrystalline titanium dioxide can be synthesised via different methods, among which chemical precipitation, microemulsion method (inversed micelles), sol-gel process and hydrothermal crystallisation are the most important ones. That is why, a crucial part of the following chapter will be paid to characterisation of synthesis routes used for titanium dioxide and titania-based hybrid production. Furthermore, application of TiO 2-based materials, including mixed oxide systems as well as graphene oxide-based hybrids, in electrochemical (electrode material) and environmental (photocatalysis) aspects, will be described in detail.
