AI Technical Summary
Existing hydrogen sensors suffer from poor selectivity, low sensitivity, high operating temperature, and poor moisture resistance, making them unsuitable for portable integrated applications.
Palladium chloride was reduced in situ to highly dispersed Pd nanoparticles via a solvothermal method, which were then loaded onto a tin-zinc bimetallic oxide. The particle size of the Pd nanoparticles was controlled to improve hydrogen dissociation capacity and interfacial chemical bonding stability, thereby reducing excessive adsorption of water molecules.
It significantly improves hydrogen response and selectivity at low operating temperatures, maintains response stability under high humidity conditions, simplifies the preparation process, and reduces energy consumption.
