Rapid hydrogen detection with low temperature realized by regulating chemisorbed oxygen species of mesoporous indium tin oxide microsphere
Source abstract
Abstract
With the quick development of hydrogen energy, it is necessary to fabricate hydrogen sensor with high sensitivity, fast response/recovery and low detection limit to monitor the leakage of hydrogen. In this work, a series of indium tin oxide (ITOs) microspheres were successfully synthesized by alkoxide precursors method. Among them, 10.7% In-doped SnO 2 (named ITO-II) based sensor exhibits high sensitivity, excellent selectivity, great stability and ultra-fast dynamic process (response time and recovery time<3 s), at a low working temperature of 200 °C. The excellent hydrogen sensing performance of ITO-II should be attributed to the increased chemisorbed oxygen and the high intrinsic reactivity of SnO 2 toward hydrogen. This work provides inspiration for the design of novel hydrogen sensing material.
