From function-guided assembly of a lotus leaf-like ZnO nanostructure to a formaldehyde gas-sensing application

Facile synthesis of ZnO/SnO2 hybrids for highly selective and sensitive detection of formaldehyde

“…The responses of all samples to HCHO within Table 1 summarizes the HCHO sensing properties of the ZnO-SnO 2 hybrids and those of the previous study. [42][43][44][45][46][47][48][49][50] Note that poor selectivity is a common problem. Fortunately, the ZnO-SnO 2 hybrid-based sensor shows excellent HCHO selectivity.…”

Facile synthesis and enhanced gas sensing properties of In2O3 nanoparticle-decorated ZnO hierarchical architectures

“…Compared with previous reports, it is found that although the response value of 3 wt% In 2 O 3 -decorated ZnO nanostructures is not very high, the optimum working temperature (240 °C) is lower than some literature reports. [42][43][44][45] In addition, the rapid response time (1 s) also shows the advantage…”

Controlled Synthesis of Hierarchically Assembled Porous ZnO Microspheres with Enhanced Gas‐Sensing Properties

“…In addition, ZnO has abundant raw materials, cheap price, no toxicity, and simple synthetic method [13], and therefore ZnO has been recognized as one of the most important promising semiconductor materials. More and more research groups have been concentrated on using ZnO as a gas sensor for a variety of gases such as NH 3 , formaldehyde, CO, H 2 S, ethanol, and NO 2 [14][15][16][17][18][19]. In recent years, many researchers have devoted themselves to synthesis of ZnO with different morphologies for special applications.…”
