Zeolitic Imidazolate Framework as Formaldehyde Gas Sensor

Abstract

Traditional semiconducting metal oxide-based gas sensors are always limited on low surface areas and high operating temperatures. Considering the high surface area and high stability of zeolitic imidazolate framework (ZIF), ZIF-67 (surface area of 1832.2 m(2) g(-1)) was first employed as a promising formaldehyde gas sensor at a low operating temperature (150 °C), and the gas sensor could detect formaldehyde as low as 5 ppm. This work develops a new promising application approach for porous metal-organic frameworks.

“…S1, see ESI ) to determine its surface and porosity. The surface area is found to be 1717 m 2 g À1 with a pore volume of 0.70 cm 3 g À1 , which is similar to the reported values in the literature (Chen et al, 2014).…”

Er-doped ZnO nanofibers for high sensibility detection of ethanol

“…Due to the rapid development of urbanization and industrialization, air pollution, which may gravely threatens the human health and safety, has become a critical global environmental issue [1][2][3][4]. To monitor the air pollution, attempts have been made to develop a variety of gas sensor using optical fibers, conducting polymers, potentiometric electrodes, infrared devices and metal oxides [5][6][7][8][9].…”
