Visible-light activate mesoporous WO3 sensors with enhanced formaldehyde-sensing property at room temperature

Detection of hazardous volatile organic compounds (VOCs) by metal oxide nanostructures-based gas sensors: A review

“…Deng et al [166] investigated the sensing properties of a commercial and mesoporous WO 3 ( Fig. 13a, b) for formaldehyde detection at room temperature under visible light.…”

Mesoporous WO3 photocatalyst for the partial oxidation of methane to methanol using electron scavengers

“…This kind of materials exhibit a large surface area that improves the adsorption of reactant molecules [8] and the ordered mesopore channels facilitate fast intraparticle molecular transfer, resulting in a decrease of charge recombination and thus, a higher photoactivity. Ordered mesoporous WO 3 has been widely studied for sensor applications [9,10,11], but limited studies have been performed for photocatalytic reactions [12,13,14]. To the best of our knowledge, there is no report on the application of ordered mesoporous WO 3 toward methane conversion by photocatalysis.…”

Self-heating effects in large arrangements of randomly oriented carbon nanofibers: Application to gas sensors

“…with micro-machined heaters mounted on thermally insulated membranes [2][3][4]. In the second case, an efficient light source (such as a LED) is integrated in the sensor device reaching power needs comparable to those of conventionally heated sensors [5][6][7][8]. In the third case, sensor active layer functionalization [9,10], material decoration [11,12] and the use of hybrid materials [11,13,14] are traditional strategies to enhance and modify the active film properties, and hence the gas-surface interaction mechanism.…”
