Abstract
This study reports hydrogen sensors based on ultra-small bimetallic palladium/magnesium (Pd/Mg) nanowires network on commercial filtration membrane. Previously, hydrogen sensors based on single Pd nanowires showed promising results in speed, sensitivity, and ultra-low power consumption. However, the utilization of single Pd nanowires faces challenges in nanofabrication, manipulation, and achieving ultra-small transverse dimensions. Compare with this, our as-fabricated sensors not only showed enhanced hydrogen sensing but also possible to use as a wearable device for real field applications. The formation of a network of discrete Pd/Mg nanowires shows hydrogen sensing properties at room temperature with remarkable amenities, such as a large detection range (10–40,000 ppm) and fast response time. For a 1 vol% H2 concentration, a response time of ∼ 6 s is observed, which is enhanced with the dealing of bending (∼ 4 s).
