Synthesis of 3D flower-like ZnSnO3 and improvement of ethanol-sensing properties at room temperature based on nano-TiO2 decoration and UV radiation

Semiconductor Metal Oxides as Chemoresistive Sensors for Detecting Volatile Organic Compounds

“…Recently, ternary oxide-based ethanol sensors have been investigated by many researchers [85,109,118,123,124,125,126]. Zhou et al prepared ZnSnO 3 hollow cubes using the co-precipitation method, followed by alkali etching and annealing under inert conditions [109].…”

Sodium alginate assisted construction of ZnSnO 3 microspheres enhanced HCHO sensing performance under UV illumination at room temperature

“…On the one hand, the remaining holes can reach the surface of ZnSnO 3 which will react with oxygen ions, leading to the width of the surface depletion layer being reduced and this causes the resistance to be decreased. On the other hand, the remaining photo‐generated electrons can react with ambient oxygen molecules, leading to photo‐induced oxygen ions [20]. When the sensors are exposed to HCHO gas, the chemical reactions between the photo‐induced oxygen ions and formaldehyde molecules may happen, making the width of the surface depletion layer further reduced with electrons released according to the following equation: Also, the properties of metal semiconductor oxide gas sensor are influenced by several factors, such as microstructure, porosity and impurities [10, 14].…”

Pressure and osmotically driven membrane processes: A review of the benefits and production of nano-enhanced membranes for desalination

“…Accordingly, different shapes and sizes of NMs are created. This includes particles (Pattnaik et al 2018), rods (Khot et al 2018), tubes (Liao et al 2018), films (Mujeeb Rahman et al 2018) and even unique structures, such as flower-like structures (Wang, Ding, Liu, Zhu, Li, Xia, Fu & Li 2018).…”
