Abstract

Microstructural evolution of spinel Zn2SnO4nanofibers was manipulated viaan in situphase separation process of inorganic precursors and a matrix polymer during electrospinning and calcination. Chemiresistive gas sensors using porous Zn2SnO4fibers exhibited superior C2H5OH sensing response. [ABSTRACT FROM AUTHOR]

Abstract

The selective detection of two different gases, NO2and C2H5OH, has been achieved using a p-type Co3O4-decorated n-type ZnO nanowire (NW) network sensor. The gas selectivity was explained by the catalytic effect of nanocrystalline Co3O4and the extension of the electron depletion layer viathe formation of p–n junctions. [ABSTRACT FROM AUTHOR]

Abstract

Ultra-fast responding and recovering C2H5OH sensors were prepared using nanoscale SnO2hollow spheres with NiO-functionalized inner walls. The exceptional ultra-fast recovery characteristics were attributed to the catalytic surface reaction assisted by NiO at the inner shell. [ABSTRACT FROM AUTHOR]
