Abstract
In this investigation, we have synthesized pure and copper decorated tin oxide nanostructures with a facile yet environment-friendly hydrothermal route. The sensing materials are characterized by X-ray diffraction, field emission scanning electron microscopy, and energy dispersive X-ray spectroscopy. Thick-film gas sensors are fabricated from the as-prepared samples, and their gas sensing performances towards sulfur dioxide are calculated and evaluated by a Chemical Gas Sensor-8 intelligent gas sensing analysis system automatically.
