The utilization of metal-organic frameworks (MOFs) as precursors or templates to design synthesize nanostructured metal oxides has attracted intense interest for their great potential applications in gas separation/storage, drug delivery, catalysis device, gas sensors, etc.
Two-dimensional (2D) micro- and nanostructured arrays have attracted much interest because of their potential applications in optoelectronic device, gas sensors, solar cell, self-cleaning surface, etc. [1 5].
Various efforts have been made to synthesize different carbon structures and morphologies due to their wide range of applications in semiconductor device, gas storage, nanotweezers and electronics [4 8].
Sensors were tested as ac dc transfer devices, gas flow meters and vacuum detectors.
The PEDOT-coated PMMA nanofiber mats prepared in this study exhibited good electrical properties and are expected to be excellent candidates for the fabrication of flexible electronic devices such as thermoelectric devices, gas sensors, and energy-storage systems.
Robust ZnO has important applications in the field of biosensors, solar cell window, surface acoustic devices, gas sensor, and piezo actuator devices[2, 3].

In this paper, we used tin dioxide because it presents great potential properties for applications such as optoelectronic devices, gas sensors, and solar energy or even for detecting leakages of reducing gases such as H, H2S, CO, and others[4].
In recent years, transparent conductive oxide (TCO) layers have been drawing considerable attention for their potential applications in photovoltaic devices, gas sensors, phototransistors and other electronic and optoelectronic devices [1].
The dopedfilms can be used for various applications such as transparent electronics,piezoelectronic devices, gas sensors, and the transparent electrode window layerof thin-film solar cells [8, 9, 10, 11, 12, 13].
In planar SOFCs and other solid-electrolyte devices, gas-tight seals must be formed along the edges of each cell and between the stack and gas manifolds.
