Synthesis and characterization of SnO2 hollow nanofibers by electrospinning for ethanol sensing properties

A highly sensitive ethanol gas sensor based on mesoporous SnO2 fabricated from a facile double-surfactant template method

“…In the measurements, the responses are 5060, 2400, 1600, 1200 for the concentrations of 200, 100, 50, 20 ppm ethanol, respectively. The sensing response to ethanol in this work is much higher than the results reported previously [16], indicating that our mesoporous SnO 2 is a promising candidate for high performance gas sensors.

Quasi-one-dimensional metal-oxide-based heterostructural gas-sensing materials: A review

“…Nanowires [90][91][92], nanofibers [93][94][95] and nanorods [96][97][98] have been grown successfully, starting from both vapor phase and solution phase. In the vapor phase growth process, the raw materials will firstly be evaporated and then condense on the surface of catalyst particles or lattice-matching substrates, which are automatically directed by the minimization of surface free energy [42,46].…”

Recent Trends in Electrospinning of Polymer Nanofibers and their Applications as Templates for Metal Oxide Nanofibers Preparation

“…The produced fibers exhibit high sensitivity, reproducibility, and quick reaction in the recognition of triacetone triperoxide (TATP) explosive precursors in the ppm scale. In addition, SnO 2 hollow nanofibers were fabricated for a high and fast detecting ethanol (C 2 H 5 OH) using polyvinylpyrrolidone (PVP) as a template, which was removed by calcination at 600°C for 2 h [76]. The produced SnO 2 nanofibers have a large surface area of 26.43 m 2 g −1 and grain sizes of about 20 nm.…”
