A coral-like SnO 2 nanostructure densely-modified with TiO 2 nanoparticles was reported for developing a self-cleaning gas sensor. The density of the TiO 2 nanoparticles in the TiO 2 /SnO 2 nanocomposites can be greatly improved via a plasma-based modification (PM) on SnO 2 /carbonaceous precursors before introducing Ti sources. In gas-sensing measurements,...
In order to sensitively detect indoor air contaminants including benzene, formaldehyde, toluene, and acetone, an effective method using a gas sensor based on coral-shaped tin dioxide nanostructures is reported. It is found that the presented gas sensor exhibits obviously enhanced sensing performance toward indoor air contaminants compared with the ones based on some conventional nanostructures, like...
Persistent organic pollutants (POPs) are greatly noxious chemicals in environment, and they can cumulate in organisms and transfer between different species. Therefore, it is significant to detect POPs for both environmental evaluation and further treatment. However, developing facile approach for the detection of POPs still remains a challenge so far. In this paper, we report an innovative method...
