Pt-Embedded Metal–Organic Frameworks Deriving Pt/ZnO-In2O3 Electrospun Hollow Nanofibers for Enhanced Formaldehyde Gas Sensing

“…Moreover, the five-repeated response/recovery curves of the 25PtZI sensor toward 100 ppm HCHO at 180 • C are tested in constant experimental conditions. As shown in Figure 4f, the response value of the 25PtZI sensor only fluctuates slightly with unchanged response/recovery times, suggesting the excellent repeatability of the 25PtZI sensor [11].…”

“…Gas sensors based on metal oxide semiconductors (MOS) (e.g., SnO 2 [7,8], In 2 O 3 [9,10], ZnO [11,12], and NiO [13,14]) have attracted great attention for volatile organic compounds detection due to their easy fabrication, simple operation, cost-effectiveness, and real-time monitoring [15]. Among them, In 2 O 3 is a significant n-type semiconductor with a wide band gap (3.55-3.75 eV) [16], and high electrical conductivity and stability (thermal and chemical), which has been proven to be an ideal material for gas sensing [17].…”

Tailoring TiO2 Interfacial by Photoinduced Calcium Deposition for Electrochemical Sensitive Detection of Bisphenol A

“…28−30 The expected deposition of metal ions on a solid surface can be achieved with the help of a suitable catalyst support and specific reaction conditions. 31,32 This process results in the generation of various-sized particles on the substrate surface. This modification not only alters the interfacial structure but also concurrently serves as in situ catalytic active sites.…”

“…Nanostructured metal oxides are emerging as effective catalysts due to their increased surface areas and the presence of low-coordinated metal and oxygen sites while enhancing the adsorption of feedstock species. , Modifying catalysts with a second metal is an efficient strategy to alter the electronic structure, thus significantly enhancing their catalytic activity. − The expected deposition of metal ions on a solid surface can be achieved with the help of a suitable catalyst support and specific reaction conditions. , This process results in the generation of various-sized particles on the substrate surface.
