摘要

为了制造高灵敏度的半导体氢传感器，采用溶胶-凝胶法制备了粒径为5-6 nm和10-11 nm的纳米二氧化锡，并在其基础上掺杂了pd材料。以含0.24%钯的纳米前草酸盐SnO2为材料制成的传感器对氢浓度的灵敏度最高。所获得的半导体传感器的高灵敏度是由表面工艺对其电阻的显著影响所解释的，因为SnO2颗粒的尺寸最小。

Nanosized Pd/SnO2 Materials for Semiconductor Hydrogen Sensors

To create highly sensitive semiconductor hydrogen sensors, nanosized tin dioxides with particle sizes of 5-6 and 10-11 nm have been obtained by the sol-gel method using various precursors, as well as Pd-doped materials on their base. The maximum sensitivity to the hydrogen microconcentrations has been found for the sensors based on the nanosized ex-oxalate SnO₂ containing 0.24% palladium. High sensitivity of the obtained semiconductor sensors is explained by the significant influence of surface processes on their electrical resistance due to the smallest sizes of the SnO₂ particles.
