“…In order to achieve an optimal sensing performance, various methods such as hydrothermal growth, template-assisted growth, chemical vapor deposition and electrospinning have been used to produce ZnO nanomaterials of different properties [19][20][21][22][23]. Among them, electrospinning has been proven to be an effective, versatile, simple and low-cost method to produce high gas sensing performances due to the ultrahigh surface-to-volume ratio [19,24]. More recently, it has been demonstrated that metallic doping could be used to improve the sensitivity of ZnO-based gas sensors [24][25][26][27][28][29][30][31].…”

Electrospun one-dimensional (1D) nanostructures are rapidly emerging as key enabling components in gas sensing due to their unique electrical, optical, magnetic, thermal, mechanical and chemical properties. 1D nanostructures have found applications in numerous areas, including healthcare, energy storage, biotechnology, environmental monitoring, and defence/security. Their enhanced specific surface area, superior mechanical properties, nanoporosity and improved surface characteristics (in particular, uniformity and stability) have made them important active materials for gas sensing applications. Such highly sensitive and selective elements can be embedded in sensor nodes for internet-of-things applications or in mobile systems for continuous monitoring of air pollutants and greenhouse gases as well as for monitoring the well-being and health in everyday life. Herein, we review recent developments of gas sensors based on electrospun 1D nanostructures in different sensing platforms, including optical, conductometric and acoustic resonators. After explaining the principle of electrospinning, we classify sensors based on the type of materials used as an active sensing layer, including polymers, metal oxide semiconductors, graphene, and their composites or their functionalized forms. The material properties of these electrospun fibers and their sensing performance toward different analytes are explained in detail and correlated to the benefits and limitations for every approach.

“…Ce 3+ possesses shielded 4f levels, which allow various well-defined narrow optical transitions between the spin-orbit levels and thus split the bandgap of ZnO into sub-gaps. For this reason, Ce 3+ is generally doped or associated to ZnO to improve the luminescence efficiency by energy transfer processes and this topic is becoming an exciting area of research for developing electronic and optical applications like sensors, light-emitting phosphors or flat panel displays [14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Due to the defects induced in the ZnO crystalline structure by Ce doping and the ability of this element to trap photogenerated charge carriers, Ce-doped ZnO (ZnO:Ce) particles have also gained high interest for photocatalysis.…”

Ce-doped ZnO (ZnO:Ce) nanorods have been prepared through a solvothermal method and the effects of Ce-doping on the structural, optical and electronic properties of ZnO rods were studied. ZnO:Ce rods were characterized by XRD, SEM, TEM, XPS, BET, DRS and Raman spectroscopy. 5% Ce-doped ZnO rods with an average length of 130 nm and a diameter of 23 nm exhibit the highest photocatalytic activity for the degradation of the Orange II dye under solar light irradiation. The high photocatalytic activity is ascribed to the substantially enhanced light absorption in the visible region, to the high surface area of ZnO:Ce rods and to the effective electron-hole pair separation originating from Ce doping. The influence of various experimental parameters like the pH, the presence of salts and of organic compounds was investigated and no marked detrimental effect on the photocatalytic activity was observed. Finally, recyclability experiments demonstrate that ZnO:Ce rods are a stable solar-light photocatalyst.
