High-yield synthesis of TiO(2) one-dimensional (1D) nanostructures was realized by a simple annealing of Ni-coated Ti grids in an argon atmosphere at 950 degrees C and 760 torr. The as-synthesized 1D nanostructures were single crystalline rutile TiO(2) with the preferred growth direction close to [210]. The growth of these nanostructures was enhanced by using catalytic materials, higher reaction temperature, and longer reaction time. Nanoscale tensile testing performed on individual 1D nanostructures showed that the nanostructures appeared to fracture in a brittle manner. The measured Young's modulus and fracture strength are ~56.3 and 1.4 GPa, respectively.
通过在950摄氏度和760托的氩气气氛中对镀镍钛网格进行简单退火，实现了TiO₂一维（1D）纳米结构的高产率合成。所合成的一维纳米结构是单晶金红石TiO₂，其择优生长方向接近[210]。使用催化材料、更高的反应温度和更长的反应时间可促进这些纳米结构的生长。对单个一维纳米结构进行的纳米级拉伸测试表明，这些纳米结构似乎以脆性方式断裂。测得的杨氏模量和断裂强度分别约为56.3和1.4吉帕。
