Abstract:
A new galvanic replacement synthetic strategy using metallic Ti as a template for hollow voids is presented and an intriguing hollow interwoven structured Sb/TiO2 is introduced. The applied Ti can play the triple role of reducing the Sb-ion into Sb, acting as a sacrificial template to generate hollow voids through a structural evolution and behaving as an alternative non-sensitive titanium salt to form TiO2. Interwoven Sb/TiO2 can be readily activated and can also buffer drastic volumetric variations during storage of alkaline ions (e.g. Li+, Na+), thereby demonstrating high capacity and superior cycling ability in rechargeable batteries.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
