Improving the selectivity of gas sensors is crucial for their further development. One effective route to enhance this key property of sensors is the use of selective nanomembrane materials. This work aims to present how metal-organic frameworks (MOFs) and thin films prepared by atomic layer deposition (ALD) can be applied as nanomembranes to separate different gases, and hence improve the selectivity of gas sensing devices. First, the fundamentals of the mechanisms and configuration of gas sensors will be given. A selected list of studies will then be presented to illustrate how MOFs and ALD materials can be implemented as nanomembranes and how they can be implemented to improve the operational performance of gas sensing devices. This review comprehensively shows the benefits of these novel selective nanomaterials and opens prospects for the sensing community.

Abstract Employing the environmentally friendly methods for synthesis of the metal-organic frameworks (MOFs) is an urgent need and sustainable development in the synthesis of these compounds is essential. In this way, ignoring the counter electrode reaction is a potentially negative point from green chemistry standpoint which increases some issues like energy consumption and reaction time. We wish to introduce the “paired electrodeposition” (PED) technique as a new method for the simultaneous synthesis and deposition of the MOF thin films (MOFTFs). This protocol implements the uniform pattern of two MOFTF modified substrates by “convergent (CPED: Zna/Znc-MOFTFs) and divergent (DPED: Cua/Znc-MOFTFs) paired electrodeposition” via a one-step synthesis. With the rule of thumb, enhanced energy efficiency and atom economy, increasing electrochemical yield, time-saving along with a variety of products are advantages of this technique. Besides, the “Electrode Modification Efficiency” has introduced for the evaluation of functionality and modification efficiency of electrochemical heterogeneous systems, especially MOFTFs. To investigate this concept, we synthesized Zn3(BTC)2 and Cu3(BTC)2 as MOF models under constant current electrolysis in water and at room temperature. This work can make a breakthrough in the green synthesis of metal-organic frameworks.
