Highly Dispersed Pt-Decorated Oxygen-Vacancy-Rich MOF-Derived SnO 2 Nanostructures on MEMS Hot Plate for ppb-Level Hydrogen Detection
Abstract
sensor (with an optimal operating temperature of 244 °C), and its power consumption is only 22.1 mW. Furthermore, this sensor demonstrates excellent comprehensive performance, including an extremely low limit of detection of 73.6 ppb, outstanding selectivity, and good long-term stability. Mechanistic studies indicate that the enhancement of gas-sensing performance is due to a combination of factors: plentiful oxygen vacancies, the role of Pt in promoting oxygen reactions, and its effect on the material's electronic properties.
