Despite the high sensitivity and selectivity, the high operating temperature required for activation energy of tin oxide (SnO 2 ) still stands as a drawback for SnO 2 based gas sensors. In this work, the SnO 2 thin films were deposited through spray pyrolysis and were subjected to gas sensing at 27 °C (room temperature) towards different gases. The films exhibited a consistently low response of approximately 1 when tested to various VOCs. The type, concentration, and mobility of charge carriers were determined from the Hall measurements. The high carrier concentration accompanied by poor mobility and grain boundary scattering is supposed to hinder its performance at room temperature. The obtained film had spherical morphology, which lead to grain boundary scatterings and decreased the mobility of carriers.

In the last decades, development of hybrid materials, especially inorganic–organic materials, coordination polymers, conducting polymers, carbon materials, and many more, has produced breakthroughs in diverse applications. Various advance materials have been reported in the literature using metal organic frameworks (MOFs), which compensate for the limitations of sensors. Diverse combinations of HMs not only offer excellent features, but also give a ray of hope for unprecedented advances in materials in different research areas, such as sensing, energy storage, catalysis, non-linear optics, drug-delivery systems, gas storage, etc. Chemiresistor sensors are a core enabling sensor technology and have led to much progress in the field of material science. Here, we have reviewed the recent progress in chemiresistive sensors based on HMs for nitroaromatic compounds, which could be beneficial for researchers that explore this field further. We have put emphasis on sensing mechanisms and the performance of diverse HMs for nitroaromatic sensing applications including pesticides, pollutants, explosives, polycyclic aromatic hydrocarbons (PAHs) and persistent organic pollutants (POPs). In the end, we explored opportunities, challenges, and future perspectives in this emerging field.
