Highly crystalline {010} facet grown α-MoO3 nanobelts for resistive sensing of n-butanol vapor at room temperature

Novel electrospun bead-like Ag2MoO4 nanofibers coated on Ni foam for visible light-driven heterogeneous photocatalysis and high-performance supercapacitor electrodes

“…4b revealed Mo 3d 5/2 and 3d 3/2 spin–orbits at 232.3 and 235.7 eV, respectively. 35,36 The Ag + ionic spin–orbits 3d 5/2 and 3d 3/2 were located at 374.4 and 368.5 eV, respectively, and the lack of elemental silver was confirmed by the extended Ag 3d XPS spectra (Fig. 4c).…”

Gas Sensing of Laser-Produced Hybrid TiO2-ZnO Nanomaterials under Room-Temperature Conditions

“…Both the response and recovery times were defined as the time taken for the sensor to reach 90% of maximum response and recover back to surface resistance in absence of target gas, respectively [ 48 ]. Such times for sample TiO 2 /ZnO were found to be 24 and 607 s, respectively, towards 100 ppm of ethanol.…”

“…For this, the values of % RH were varied to 32% and 72% from the actual relative humidity of 56%, which was achieved by maintaining corresponding saturated salt solutions of MgCl 2 and NaCl inside the sensing chamber [ 49 ]. Humidity was evaluated by a digital humidity and temperature sensor (DHT 11) integrated into the sensing chamber used [ 43 , 48 ]. The sensing response was found to increase by 10 and 28% at lower humidity (32% RH) for 2-propanol and ethanol, respectively (see Figure 8 a).…”

A critical insight into porous organic polymers (POPs) and its perspectives for next-generation chemiresistive exhaled breath sensing: a state-of-the-art review

“…Considering the roadmap of the materials explored for chemiresistive sensing, metal oxides 23,33,34 have been widely investigated over several decades. Nevertheless, it possesses good sensing characteristics; the undesired dris in the selectivity and elevated operating temperature make them the least appropriate for practical exposures.…”
