3-dimensional nanostructured ZnO gas sensor

Conductive Photo-Activated Porphyrin-ZnO Nanostructured Gas Sensor Array

Chemoresistors working at room temperature are attractive for low-consumption integrated sensors. Previous studies show that this feature can be obtained with photoconductive porphyrins-coated ZnO nanostructures. Furthermore, variations of the porphyrin molecular structure alter both the chemical sensitivity and the photoconductivity, and can be used to define the sensor characteristics. Based ...

Synthesis and gas sensor applications of nanostructured ZnO grown at low temperatures

ZnO nanoarchitecture-based nanoand microdevices came into the focus due to their multifunctional operation. In this work, we summarize cost-effective procedures to grow ZnO nanoand microstructures, namely hydrothermal growth and electrochemical deposition. These techniques allow the controllable growth of ZnO nanoand microarchitectures at relatively low temperatures, below 100 ◦C, and do not re...

ZnO Nanowires/Nanobelts Structured CO Gas Sensor

Zinc oxide nanowires/nanobelts thin films were prepared by thermal evaporation deposition of Zn on two different kinds of substrates, namely Cr-glass and Cr-<100> n-type Si. ZnO nanostructured based COgas sensing thin films were formed, and the morphologies of these films were investigated by scanning electron microscopy (SEM). The sensing response of the films toward CO gas at operating temper...
