One-dimensional nanostructures are generally cited as nanowires, nanofibers, nanotubes, and so on. The foremost prominent feature of these materials is their electrical conductivity, which, unlike classical physics, doesn't increase resistance because the diameter decreases. Numerous properties like optical, magnetic, biological, environmental sensory have created many applications for them altogether industries. nanowires (NWs) propose potential impact on electronics, computing, memory, data storage, communications, manufacturing, health, medicine, national security, other economic sectors well. NWs offer excellent surface-to-volume ratio (interface phenomena), low defect density, high optical output, controllable n-type making more appropriate sensitive sensing applications. with ultra-sensitive real-time detection capabilities lend in nano biosensors, chemical sensors, gas electrochemical sensors. been used improving absorption well collection efficacy photovoltaic devices. having small size, weight, cost mass production, also compatible commercial planar processes large-scale circuitry.

Development of lithium-ion batteries (Li-ion batteries) with high safety and solidity features has become a main challenge researchers when practical implementations for large-scale energy storage systems are prioritized. In this work, we introduce useful efficient strategy to manufacture long-standing high-rate carbon-doped TiO2 (C-TiO2) as an anode material. Titanium (TiO2) C-TiO2 were successfully prepared through hydrothermal method in order improve the electrical performance Li-battery. The structure thermal properties investigated by XRD, Raman TGA; whereas evaluated Glvanostatic discharge–charge measurements. density function theory (DFT) results revealed that doped carbon atoms causes considerable stress inside crystal lattice TiO2, avoid or minimize underwent relaxation then optimized. electrodes Li-battery was analyzed 100 cycles at different calcination temperatures 400 450 °C. also showed charge capacities 500 mAhg−1 mAg−1.
