The sensors based on ZnO tetrapods (T-ZnO) and ZnO tetrapods with TiO2 mixing (T-TiZnO) and Au coating (Au/T-TiZnO) were investigated. The T-ZnO and T-TiZnO were synthesized by a simple thermal oxidation technique. The leg of the tetrapod is about 1-10 μm in length and 160-500 nm in diameter. Au coa...
