Abstract:Real-time monitoring of carbon monoxide (CO) is crucial for ensuring human safety. However, the accuracy of the CO detection is significantly diminished by high ambient humidity. This study focuses on synthesizing CeO 2 /In 2 O 3 hollow nanospheres with varying CeO 2 contents (0, 1, 2, 3 mol %) using a twostep method. Testing under different humidity conditions demonstrates that incorporating CeO 2 not only amplifies the response rate of pure In 2 O 3 sensors (from 1.4 to 1.65 at 100 ppm of CO) but also curtai… Show more
