Room temperature gas sensors based on MOF-derived metal oxides: An overview
Resistive gas sensors with high specific surface area (SSA) and porous nature are highly favorable for gas detection studies thanks to providing of numerous anchoring sites for gases and also diffusion channels for fast gas transportation. Metal organic frameworks (MOFs) with crystalline nature and high SSA, and porous nature can be annealed at high temperatures to produce metal oxides with similar morphology of corresponding MOFs. Accordingly, MOF-derived metal oxides are highly promising for sensing applications. Operation at high temperatures leads higher safety related to the detection of explosive gases and longer stability of sensor. Room temperature (RT) operation provides a good opportunity to develop extremely low power consumption gas sensors and also avoid complexity of electronic circuits. Furthermore, agglomeration of sensing material particles can be avoided at RT, leading to better sensing capability. Herein, we describe RT gas sensing features of MOF-derived metal oxides. MOF-derived metal oxides may be in single phase, nanocomposite, doped, and decorated states. We believe that this paper can open new avenues for those actively work in this hot field.
