Hollow In2O3@TiO2 double-layer nanospheres were prepared via a facile water bath method using the sacrifice template of carbon nanospheres. It is shown that size In2O3/TiO2 nanocomposites 150-250 nm, thickness In2O3 shell about 10 and TiO2 15 nm. The sensing performances synthesized nanocomposites-based chemiresistive-type sensor to formaldehyde (HCHO) gas under UV light activation at room temperature have been studied. Compared pure In2O3- TiO2-based sensors, nanocomposite exhibits much...
Au modified TiO2/In2O3 hollow nanospheres were synthesized by the hydrolysis method using carbon as a sacrificial template. Compared to pure In2O3, TiO2, and based sensors, Au/TiO2/In2O3 nanosphere-based chemiresistive-type sensor exhibited excellent sensing performances formaldehyde at room temperature under ultraviolet light (UV-LED) activation. The response of nanocomposite-based 1 ppm was about 5.6, which is higher than that In2O3 (1.6), TiO2 (2.1), (3.8). time recovery nanocomposite 18...
In2O3@TiO2 core-shell nanocubes were successfully prepared via hydrothermal method and subsequent water bath method. The characterization results show that the size of nanocomposites is 250-350 nm. based sensor presents excellent sensing response to formaldehyde at ppb level. 1 ppm about 5.3 room temperature under UV activation, which three times higher than pure In2O3 sensor. response/recovery time are 24 s 52 s, respectively. involved chemical reactions activated by had been investigated...
